      Time other than any Dissenting Shares (as defined and to the extent
      provided in Section 1.8(a)) will be canceled and extinguished and be
      converted automatically into the right to receive that number of shares of
      BESC Common Stock determined by application of the Exchange Ratio (as
      defined below), upon surrender of the certificate representing such share
      of JDA Common Stock in the manner provided in this Section 1.7.

      indirect wholly owned subsidiary of BESC or of JDA outstanding immediately

  (d) JDA Stock Purchase Options or Other Rights.
      At the Effective Time, any rights theretofore outstanding to acquire any
      JDA Common Stock, such as options, warrants, convertible debt or other
      rights shall have been fully exercised or terminated.

  (e) Adjustments to Exchange Ratio.
      The Exchange Ratio shall be adjusted to reflect fully the effect of any
      stock split, reverse split, stock dividend (including any dividend or
      distribution of securities convertible into BESC Common Stock),
      reorganization, recapitalization or other like change with respect to BESC
      Common Stock occurring after the date hereof and prior to the Effective
      Time.

  (f) Fractional Shares.
      No fraction of a share of BESC Common Stock will be issued, but in lieu
      thereof each holder of shares of JDA Stock who would otherwise be entitled
      to a fraction of a share of BESC Common Stock (after aggregating all
      fractional shares of BESC Common Stock to be received by such holder)
      shall be entitled to receive from BESC a whole share of BESC Common Stock.

  (g) Definitions.
      (i) Exchange Ratio. The "Exchange Ratio" shall be the quotient obtained by
      dividing the number of BESC Transaction Shares by the number of shares of
      JDA Common Stock outstanding as of the Effective Time. (ii) Escrow Shares.
      The "Escrow Shares" shall consist of the following number of BESC
      Transaction Shares issuable at the Closing: 80% of BESC Transaction Shares
      issuable to Kennedy; 80% of the BESC Transaction Shares issuable to Jeff
      Franco; and all of the BESC Transaction Shares issuable to Green and to
      Lowe respectively.

1.8 Dissenting Shares.

a. Notwithstanding any provision of this Agreement to the contrary, any shares
of capital stock of JDA held by a holder who has demanded and perfected
appraisal rights for such shares in accordance with Maryland Law and who, as of
the Effective Time, has not effectively withdrawn such appraisal rights
("Dissenting Shares"), shall not be converted into or represent a right to
receive BESC Common Stock pursuant to Section 1.7, but the holder thereof shall
only be entitled to such rights as are granted by Maryland Law.

                                       4
<PAGE>

b. Notwithstanding the provisions of subsection 1.8(a), if any holder of shares
of capital stock of JDA who demands appraisal of such shares under Maryland Law
shall effectively withdraw the right to appraisal, then, as of the later of the
Effective Time and the occurrence of such event, such holder's shares shall
automatically be converted into and represent only the right to receive BESC
Common Stock, without interest thereon, upon surrender of the certificate
representing such shares.

c. JDA shall give BESC (i) prompt notice of any written demands for appraisal of
any shares of capital stock of JDA, withdrawals of such demands, and any other
instruments served pursuant to Maryland Law and received by JDA and (ii) the
opportunity to participate in all negotiations and proceedings which take place
prior to the Effective Time with respect to demands for appraisal under Maryland
Law. JDA shall not, except with the prior written consent of BESC, voluntarily
make any payment before the Effective Time with respect to any demands for
appraisal of capital stock of JDA or offer to settle or settle any such demands.

1.9 Surrender of Certificates.

1.9.1 BESC to Provide Common Stock.

Promptly after the Effective Time, BESC shall make available to the JDA
Shareholder Agent (hereinbelow defined) for exchange in accordance with this
Article I the shares of BESC Common Stock issuable pursuant to Section 1.7 to be
exchanged for outstanding shares of JDA Common Stock pursuant to this Agreement,
duly endorsed for transfer.

1.9.2 Exchange Procedures.

At the Closing, the JDA Shareholder Agent shall deliver to Oncologix a
certificate or certificates (the "JDA Certificates") which immediately prior to
the Effective Time represented outstanding shares of JDA Common Stock whose
shares were converted into the right to receive shares of BESC Common Stock
pursuant to Section 1.8. Delivery shall be effected, and risk of loss and title
to the JDA Certificates shall pass only upon delivery of the JDA Certificates to
Oncologix in such form and subject to such other conditions as BESC may
reasonably specify. Upon surrender of a JDA Certificate for cancellation to
Oncologix or to such other agent or agents as may be appointed by BESC, duly
completed and validly executed in accordance with the instructions thereto, the
holder of such Certificate shall be entitled to receive in exchange therefor a
certificate representing the number of whole shares of BESC Common Stock (less
the number of shares of BESC Common Stock, if any, to be deposited in the Escrow
(defined in Section 1.10, below) on such holder's behalf pursuant to paragraph
1.10, to which such holder is entitled pursuant to Section 1.7, and the
Certificate so surrendered shall forthwith be canceled. As soon as practicable
after the Effective Time, and subject to and in accordance with the provisions
of Sections 1.10 and 1.11 hereof, BESC shall cause to be delivered to the Escrow
Agent (as defined in Section 1.10) a certificate or certificates representing
that number of shares of BESC Common Stock equal to the applicable number of
Escrow Shares. Such shares shall be beneficially owned by the holders on whose

                                       5
<PAGE>

behalf such shares were deposited in the Escrow and shall be registered in the
names of the respective JDA shareholders entitled thereto and delivered to them
upon satisfaction of the conditions proved in Section 1.11, below. Until so
surrendered, each outstanding Certificate that, prior to the Effective Time,
represented shares of JDA Common Stock will be deemed from and after the
Effective Time, for all corporate purposes, to evidence the ownership of the
number of full shares of BESC Common Stock into which such shares of JDA Common
Stock shall have been so converted in accordance with Section 1.7.

1.10 Escrow

As soon as practicable after the Effective Time, the Escrow Shares (as defined
in paragraph 1.7(g)(iii)), plus any additional New Shares (as defined in the
Exhibits specified below in this Section 1.10) as may be issued in respect
thereof (such as, for example, a dividend payable in shares of capital stock)
after the Closing (collectively, the "Escrow Shares"), without any act of any
stockholder, will be registered in the names of Jeff Franco, Andrew S. Kennedy,
Andrew Green and Adam Lowe, and will be deposited with Hodes, Ulman, Pessin &
Katz, P.A. (or other institution acceptable to BESC and the JDA Shareholder
Agent (as defined below) as Escrow Agent (the "Escrow Agent"), to be governed by
the terms set forth in the Escrow Agreements respectively attached hereto as
Exhibits 1.10a, 1.10b, 1.10(c) and 1.10(d) at BESC's sole cost and expense. The
number of BESC Transaction Shares in the Escrow contributed on behalf of each
stockholder of JDA is listed opposite such stockholders' name on Schedule 2.3(a)
attached hereto.

1.11 Performance Release of Shares from Escrow

(a) The Escrow Shares shall be released from the Escrow upon the occurrence of
certain events ("Milestones") as follows, the terms, "Development Phase",
"Pre-Clinical Testing Phase" and "Clinical Approval Phase", each to have the
meaning defined below. Each Milestone will be deemed to have been attained when
so certified in writing by the Chief Executive Officer, Chief Operating Officer
and Chief Medical and Scientific Officer in the form shown by Exhibit 1.11 (a)
attached hereto.

(b) The ultimate goal for the JDA Business is to gain approval of the U.S. Food
and Drug Administration ("FDA") to market a certain microsphere product for the
treatment of liver cancer. There are numerous interim goals, or "Milestones",
that are required to be completed in order to reach this ultimate goal. The
following described Milestones, called respectively the Development Phase, the
Pre-Clinical Testing Phase, and the clinical Approval Phase, are considered the
most significant in that their realization is required to move from one phase to
another.

     (i) Development Phase. The Development Phase is the portion of the project
     that defines the design, the overall process, and the manufacturing
     feasibility of the product. At the end of this phase there is reasonable
     scientific and engineering assurance that a design is feasible, the
     processes to produce that design are reproducible, and that the design can
     be manufactured in scalable quantities at reasonable costs. The successful
     completion of this phase will allow the JDA Business to begin Pre-Clinical
     Testing. This phase will be considered completed when:

                                       6
<PAGE>

          (A) A microsphere specification and design are defined that meet the
     user requirements as defined in the Product Requirements Document;

          (B) Manufacturing lots are able to be manufactured at pilot plant
     scale (lots sizes that would be large enough to support an animal study and
     a pivotal clinical study; and

          (C) A preliminary manufacturing plan, based on reasonable assumptions,
     is documented that supports a commercially acceptable cost basis for
     commercial quantities.

     (ii) Pre-Clinical Testing Phase. The Pre-Clinical Testing phase is the
     portion of the project in which the design is verified against its "product
     (user) requirements" and the hazards of its use are identified in a risk
     analysis. This testing is required by the FDA and ISO standards for
     initiation of a clinical trial and is a necessary part of good engineering
     development and safety. These results will be required to be included in
     the IDE submission to the FDA requesting approval to initiate the treatment
     of patients in a pivotal clinical trial. The trial design and final
     specifications should be based on discussions with and preliminary advice
     from the FDA.

     The animal study will be the last pre-clinical test performed before the
     submission of the IDE to the FDA. The purpose of the animal study will be
     to:

          (A). Confirm that radiation effects from the microspheres produce
     expected local effect in the liver, without effects on other tissues or
     organs;

          (B), Document and describe any acute and chronic adverse events;

          (C). Document and describe feasibility of the delivery of microspheres
     to the liver without gastric, duodenal or pulmonary uptake; and

          (D). Document and describe the any potential liver toxicity. This
     Subparagph (D) will be considered completed when a report is finalized for
     an animal study that meets industry and scientific standards to support the
     submission of an IDE to the FDA requesting approval for a "pivotal
     clinical" trial.

     The Pre-Clinical Testing Phase will be deemed complete when the foregoing
     purposes have been accomplished.

     (iii). Clinical Approval Phase. The clinical Approval Phase is the phase of
     the project in which the IDE submission is compiled, submitted to the FDA,
     and an approval to start the "pivotal clinical trial" is granted. Once the
     design verification is completed in the Pre-Clinical Testing Phase, the IDE
     can be compiled and submitted. The FDA responds to IDE submissions within
     30 days with an approval, conditional approval, or disapproval. An approval
     or conditional approval will allow JDA to begin the treatment of patients
     in the "pivotal clinical trial".

This phase will be considered completed when the FDA letter granting approval or
conditional approval is received.

out-of-pocket expenses incurred by the JDA Shareholder Agent as a result of his
acting as the JDA Shareholder Agent.

<PAGE>

University of Maryland, Baltimore) shall severally indemnify the JDA Shareholder
Agent and hold him harmless against any loss, liability or expense incurred
without negligence or bad faith on his part and arising out of or in connection
with his acceptance or administration of the JDA Shareholder Agent's duties
hereunder, including the reasonable fees and expenses of any legal counsel
retained by him.

1.12.3 Acts of Agent Binding.

A decision, act, consent or instruction of the JDA Shareholder Agent shall
constitute a decision of all the stockholders for whom shares of BESC Common
Stock otherwise issuable to them are deposited in the Escrow and shall be final,
binding and conclusive upon each of such stockholders, and the Escrow Agent and
BESC may rely upon any such decision, act, consent or instruction of the JDA
Shareholder Agent as being the decision, act, consent or instruction of each
every such stockholder of JDA. The Escrow Agent and BESC are hereby relieved
from any liability to any person for any acts done by them in accordance with
such decision, act, consent or instruction of the JDA Shareholder Agent.

stolen or destroyed certificates, upon the making of an affidavit of that fact
by the holder thereof, such shares of BESC Common Stock, if any, as may be
required pursuant to Section 1.9; provided, however, that BESC may, in its
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificates to deliver a bond in such
sum as it may reasonably direct as indemnity against any claim that may be made
against BESC with respect to the certificates alleged to have been lost, stolen
or destroyed.

1.15 Tax Consequences.

It is intended by the parties hereto that the Merger shall constitute a
reorganization within the meaning of Section 368 of the Code.

1.16 Taking of Necessary Further Action.

If, at any time after the Effective Time, any such further action is necessary
or desirable to carry out the purposes of this Agreement and to vest Oncologix
with full right, title and possession to all assets, property, rights,
privileges, powers and franchises of JDA and Oncologix, the officers and
directors of JDA and Oncologix are fully authorized in the name of their
respective corporations or otherwise to take, and will take, all such lawful and

2.10 Tax and Other Returns and Reports.

2.10.1 Tax Returns and Audits.

JDA has accurately prepared and timely filed all required federal, state, local
and foreign returns, estimates, information statements and reports ("Returns")
relating to any and all Taxes relating or attributable to JDA or its operations
and such Returns are true and correct in all material respects and have been
completed in accordance with applicable law in all material respects. For the
purposes of this Agreement, a "Tax" or, collectively, "Taxes," means any and all
federal, state, local and foreign taxes, assessments and other governmental
charges, duties, impositions and liabilities, including taxes based upon or
measured by gross receipts, income, profits, sales, use and occupation, and
value added, ad valorem, transfer, franchise, withholding, payroll, recapture,
employment, excise and property taxes, together with all interest, penalties and

                                       13
<PAGE>

additions imposed with respect to such amounts and any obligations under any
agreements or arrangements with any other person with respect to such amounts.
JDA has timely paid all Taxes required to be paid with respect to such Returns
and has withheld with respect to its employees all federal and state income
taxes, FICA, FUTA and other Taxes it is required to withhold. The accruals for
Taxes on the books and records of JDA are sufficient to discharge the Taxes for
all periods (or the portion of any period) ending on or prior to the Closing
Date. JDA has not been delinquent in the payment of any Tax nor, except as set
forth in Schedule 2.10(a), is there any Tax deficiency outstanding, proposed or
assessed against JDA, nor has JDA executed any waiver of any statute of
limitations on or extending the period for the assessment or collection of any
Tax. No audit or other examination of any Return of JDA is presently in
progress. Except as set forth in Schedule 2.10(a), JDA does not have any
liabilities for unpaid federal, state, local and foreign Taxes, whether asserted
or unasserted, known or unknown, contingent or otherwise and JDA has no
knowledge of any basis for the assertion of any such liability attributable to
JDA, or their respective assets or operations. JDA is not (nor has it ever been)
required to join with any other entity in the filing of a consolidated tax
return for federal tax purposes or a consolidated or combined return or report
for state tax purposes. JDA is not a party to or bound by any tax indemnity, tax
sharing or tax allocation agreement. JDA has provided, or made available, to
BESC or its legal counsel copies of all federal, provincial and state income and
all sales and use Tax Returns of JDA for all periods since their respective
dates of incorporation. There are (and as of immediately following the Closing
there will be) no liens on the assets of JDA relating to or attributable to
Taxes. JDA has no knowledge of any basis for the assertion of any claim which,
if adversely determined, would result in liens on the assets of JDA. There is no
contract, agreement, plan or arrangement, including but not limited to the
provisions of this Agreement, covering any employee or former employee of JDA
that, individually or collectively, could give rise to the payment of any amount
that would not be deductible pursuant to Sections 280G, 162 or 404 of the
Internal Revenue Code of 1986, as amended ("Code"). 2.10.2 No Penalty.
JDA is not subject to any penalty by reason of a violation of any order, rule or
regulation of, or a default with respect to any return, report or declaration
required to be filed with, any Governmental Entity to which it is subject, which
violations or defaults, individually or in the aggregate, would have a Material
Adverse Effect on JDA.

2.11 Restrictions on Business Activities.

Except as otherwise disclosed in this Agreement or any of the Schedules hereto,
there is no agreement (assuming the parties thereto other than JDA performed
their respective obligations thereunder as required), judgment, injunction,
order or decree binding upon JDA which has or could reasonably be expected to
have the effect of materially prohibiting or materially impairing any business
practice of JDA, any Oncologix of property by JDA or the conduct of business by
JDA as currently conducted or as currently proposed to be conducted after the
Effective Time.

2.12 Title to Properties: No Liens or Encumbrances: Condition of Equipment.

2.12.1 JDA owns no real property. Schedule 2.12.1 sets forth a true and complete
list of all real property leased by JDA and the aggregate annual rental or other
fee payable under any such lease. To the knowledge of JDA, all such leases are
in good standing, valid and effective in accordance with their respective terms,
and there is not with respect to JDA and, to the knowledge of JDA, any other
parties to such leases, under any of such leases, any existing default or event
of default (or event which with notice or lapse of time, or both, would
constitute a default and in respect of which JDA has not taken adequate steps to
prevent such default from occurring), except where the lack of such good
standing, validity and effectiveness or the existence of such default or event
of default would not have a Material Adverse Effect on JDA.

2.12.2 JDA holds good and valid title to, or, in the case of leased properties
and assets, valid leasehold interests in, all of its tangible properties and
assets, real, personal and mixed, used in its business, free and clear of any
liens, charges, pledges, security interests or other encumbrances, except as
reflected in JDA Financial Statements and except for such imperfections of title
and encumbrances, if any, which are not substantial in character, amount or
extent, and which do not materially detract from the value, or interfere with
the present use, of the property subject thereto or affected thereby.

2.12.3 The equipment (the "Equipment") owned or leased by JDA is listed in
Schedule 2.12(c), except individual pieces of equipment owned by JDA with an
individual value of less than $500. The Equipment is, taken as a whole, (i) to
the knowledge of JDA, adequate for the conduct of the business of JDA consistent
with its past practice, (ii) suitable for the uses to which it is currently
employed, (iii) in good operating condition, (iv) regularly and properly
maintained, reasonable wear and tear excepted and (v) not obsolete, dangerous or
in need of renewal or replacement, except for renewal or replacement in the
ordinary course of business.

2.13 Intellectual Property.

2.13.1 Rights.

JDA owns, or is licensed to use, all patents, trademarks, trade names, service
marks, copyrights, and any applications therefor, maskworks, net lists,
schematics, technology, know-how, computer software programs or applications and
tangible or intangible proprietary information or material (excluding Commercial
Software Rights (as defined in paragraph (b) below)) that are used or currently
proposed to be used in the business of JDA as currently conducted or as
currently proposed to be conducted (the "JDA Intellectual Property Rights").
Schedule 2.13 sets forth a complete list of all patents, trademarks, registered
and material unregistered copyrights, trade names and service marks, and any
applications therefor, included in JDA Intellectual Property Rights, and
specifies the jurisdictions in which each such JDA Intellectual Property Right
has been issued or registered or in which an application for such issuance and
registration has been filed, including the respective registration or
application numbers and the names of all registered owners, together with a list
of all of JDA's currently marketed software products and an indication as to


                                       15
<PAGE>

which, if any, of such software products have been registered for copyright
protection with the United States Copyright Office and any foreign offices and
by whom such items have been registered. Schedule 2.13 also sets forth a
complete list of (i) any requests JDA has received to make any such
registration, including the identity of the requestor and the item requested to
be so registered, and the jurisdiction for which such request has been made and
(ii) all licenses, sublicenses and other agreements as to which JDA is a party
and pursuant to which JDA or any other person is authorized to use any JDA
Intellectual Property Right or other trade secret material to JDA, and includes
the identity of all parties thereto, a description of the nature and subject
matter thereof, the applicable royalty and the term thereof. JDA is not, nor
will it be as a result of the execution and delivery of this Agreement or the
performance of its obligations hereunder, in violation of any license,
sublicense or agreement described on such list. JDA is the sole and exclusive
owner or licensee of, with all right, title and interest in and to (free and
clear of any liens or encumbrances), JDA Intellectual Property Rights, and has
sole and exclusive rights (and, except as otherwise disclosed herein or in any
Schedule hereto, is not contractually obligated to pay any compensation to any
third party in respect thereof) to the use thereof or the material covered
thereby in connection with the services or products in respect of which JDA
Intellectual Property Rights are being used. No claims with respect to JDA
Intellectual Property Rights have been asserted or, to the knowledge of JDA, are
threatened by any person, nor, to the knowledge of JDA, is there any valid
grounds for any bona fide claims (i) to the effect that the manufacture, sale,
licensing or use of any product as now used, sold or licensed or proposed for
use, sale or license by JDA infringes on any copyright, patent, trade mark,
service mark or trade secret, (ii) against the use by JDA of any trademarks,
trade names, trade secrets, copyrights, patents, technology, know-how or
computer software programs and applications used in JDA's business as currently

copyright, patent, trade mark, service mark or trade secret, (ii) against the
use by JDA of any trademarks, trade names, trade secrets, copyrights, patents,

is made pursuant to this Section 5.2 that effect any registration with respect
to all or a part of the Registrable Securities having a reasonably anticipated
aggregate offering price, net of underwriting discounts and commissions, that
exceeds $250,000, BESC will:

     (a) promptly give written notice of the proposed registration to all other
     Holders; and

     (b) as soon as practicable, use its best efforts to effect such
     registration (including, without limitation, filing post-effective
     amendments, appropriate qualifications under applicable blue sky or other
     state securities laws and appropriate compliance with the Securities Act)
     as would permit or facilitate the sale and distribution of all or such
     portion of such Registrable Securities as are specified in such request,
     together with all or such portion of the Registrable Securities of any
     Holder or Holders joining in such request as are specified in a written
     request received by BESC within twenty (20) days after such written notice
     from the Company is effective; provided that BESC shall register up to
     200,000 shares held by the University of Maryland, Baltimore, at its
     request, without regard to any of the conditions provided above in this
     Section 5.2.1. BESC shall not be obligated to effect, or to take any action

          (A) In any particular jurisdiction in which BESC would be required to
     execute a general consent to service of process in effecting such
     registration, qualification or compliance, unless BESC is already subject
     to service in such jurisdiction and except as may be required by the
     Securities Act;

                                       30
<PAGE>

          (B) After BESC has effected three such registrations pursuant to this
     Section 5.2) and such registrations have been declared or ordered
     effective;

          (C) During the period starting with the date sixty (60) days prior to
     BESC's good faith estimate of the date of filing of, and ending on a date
     one hundred eighty (180) days after the effective date of, a registration
     pursuant to Section 5.3 hereof; provided that it is actively employing in
     good faith all reasonable efforts to cause such registration statement to
     become effective;

5.2.2 Registration Statement

Subject to the foregoing clauses (A) through (C) of Section 5.2.1, BESC shall
file a registration statement covering the Registrable Securities so requested
to be registered as soon as practicable after receipt of the request or requests
of the Initiating Holders; provided, however, that if (i) in the good faith
judgment of the Board of Directors of BESC, such registration would be seriously
detrimental to BESC and the Board of Directors of BESC concludes, as a result,
that it is essential to defer the filing of such registration statement at such
time, and (ii) BESC shall furnish to such Holders a certificate signed by the
president of BESC stating that in the good faith judgment of the Board of
Directors of BESC, it would be seriously detrimental to BESC for such
registration statement to be filed in the near future and that it is, therefore,
essential to defer the filing of such registration statement, then BESC shall
have the right to defer such filing for the period during which such disclosure
would be seriously detrimental, provided, that BESC may not defer the filing for
a period of more than one hundred eighty (180) days after receipt of the request
of the Initiating Holders, and, provided further, that (except as provided in
clause (c) above) BESC shall not defer its obligation in this manner more than
once in any twelve-month period. The registration statement filed pursuant to
the request of the Initiating Holders may, subject to the provisions of this
Section 5.2, include other securities of BESC and may include securities of BESC
being sold for the account of BESC.

5.2.3 Underwriting.

If the Initiating Holders intend to distribute the Registrable Securities
covered by their request by means of an underwriting, they shall so advise BESC
as a part of their request made pursuant to this Section 5.2 and BESC shall
include such information in the written notice referred to in Section
5.2.1(a)above. The right of any Holder to registration pursuant to this Section
5.2 shall be conditioned upon such Holder's participation in such underwriting
and the inclusion of such Holder's Registrable Securities in the underwriting
(unless otherwise mutually agreed by a majority in interest of the Initiating
Holders and such Holder with respect to such participation and inclusion) to the
extent provided herein. A Holder may elect to include in such underwriting all
or a part of the Registrable Securities he holds.

5.2.4 Procedures.

If BESC shall request inclusion in any registration pursuant to this Section 5.2
of securities being sold for its own account, or if other persons shall request
inclusion in any registration pursuant to this Section 5.2, the Initiating
Holders shall, on behalf of all Holders, offer to include such securities in the
underwriting and may condition such offer on their acceptance of the further
applicable provisions of this Article V (including Section 5.12). BESC shall

                                       31
<PAGE>

(together with all Holders, and other persons proposing to distribute their
securities through such underwriting) enter into an underwriting agreement in
customary form with the representative of the underwriter or underwriters
selected for such underwriting by a majority in interest of the Initiating
Holders, which underwriter(s) are reasonably acceptable to BESC. Notwithstanding
any other provision of this Section 5.2, if the representative of the
underwriters advises the Initiating Holders in writing that marketing factors
require a limitation on the number of shares to be underwritten, the number of
shares to be included in the underwriting or registration shall be allocated as
set forth in Section 5.13 hereof. If the person who has requested inclusion in
such registration as provided above does not agree to the terms of any such
underwriting, such person shall be excluded therefrom by written notice from
BESC, the underwriter or the Initiating Holders. The securities so excluded
shall also be withdrawn from registration. Any Registrable Securities or other
securities excluded shall also be withdrawn from such registration. If shares
are so withdrawn from the registration and if the number of shares to be
included in such registration was previously reduced as a result of marketing
factors pursuant to this Section 5.2(d), then BESC shall offer to all holders
who have retained rights to include securities in the registration the right to
include additional securities in the registration in an aggregate amount equal
to the number of shares withdrawn, with such shares to be allocated among such
Holders requesting additional inclusion in accordance with Section 5.13.

5.3 Expenses of Registration.

All Registration Expenses incurred in connection with any registration,
qualification or compliance pursuant to Section 5.2, and reasonable fees of one
counsel for the selling stockholders shall be borne by BESC; provided, however,
that if the Holders bear the Registration Expenses for any registration
proceeding begun pursuant to Section 5.2 and subsequently withdrawn by the
Holders registering shares therein, such registration proceeding shall not be
counted as a requested registration pursuant to Section 5.2 hereof, except in
the event that such withdrawal is based upon material adverse information
relating to that is different from the information known or available (upon
request from BESC or otherwise) to the Holders requesting registration at the
time of their request for registration under Section 5.2, in which event such
registration shall not be treated as a counted registration for purposes of
Section 5.2 hereof, even though the Holders do not bear the Registration
Expenses for such registration. All Selling Expenses relating to securities so
registered shall be borne by the holders of such securities pro rata on the
basis of the number of shares of securities so registered on their behalf.

5.4 Registration Procedures.

In the case of each registration effected by pursuant to Section 5.2, BESC will
keep each Holder advised in writing as to the initiation of each registration
and as to the completion thereof. At its expense, the Company will use its best
efforts to:

     (a) Keep such registration effective for a period of one hundred twenty
     (120) days or until the Holder or Holders have completed the distribution
     described in the registration statement relating thereto, whichever first

                                       32
<PAGE>

     occurs; provided, however, that such 120-day period shall be extended for a
     period of time equal to the period the Holder refrains from selling any
     securities included in such registration at the request of an underwriter
     of Common Stock (or other securities) of BESC

     (b) Prepare and file with the Commission such amendments and supplements to
     such registration statement and the prospectus used in connection with such
     registration statement as may be necessary to comply with the provisions of
     the Securities Act with respect to the disposition of all securities
     covered by such registration statement;

     (c) Furnish such number of prospectuses and other documents incident
     thereto, including any amendment of or supplement to the prospectus, as a
     Holder from time to time may reasonably request;

     (d) Notify each seller of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Securities Act of the happening of any
     event as a result of which the prospectus included in such registration
     statement, as then in effect, includes an untrue statement of a material
     fact or omits to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading or incomplete in
     the light of the circumstances then existing, and at the request of any
     such seller, prepare and furnish to such seller a reasonable number of
     copies of a supplement to or an amendment of such prospectus as may be
     necessary so that, as thereafter delivered to the purchasers of such
     shares, such prospectus shall not include an untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein not misleading or incomplete in
     the light of the circumstances then existing;

     (e) Cause all such Registrable Securities registered pursuant hereunder to
     be listed on each securities exchange on which similar securities issued by
     the Company are then listed;

     (f) Provide a transfer agent and registrar for all Registrable Securities
     registered pursuant hereunder and a CUSIP number for all such Registrable
     Securities, in each case not later than the effective date of such
     registration;

     (g) Otherwise use its best efforts to comply with all applicable rules and
     regulations of the Commission, and make available to its security holders,
     as soon as reasonably practicable, an earnings statement covering the
     period of at least twelve months, but not more than 18 months, beginning
     with the first month after the effective date of the Registration
     Statement, which earnings statement shall satisfy the provisions of Section
     10(a) of the Securities Act; and

     (h) In connection with any underwritten offering pursuant to a registration
     statement filed pursuant to Section 5.2 hereof, BESC will enter into an
     underwriting agreement reasonably necessary to effect the offer and sale of
     Common Stock, provided such underwriting agreement contains customary
     underwriting provisions and provided further that if the underwriter so
     requests the underwriting agreement will contain customary contribution
     provisions.

5.5 Indemnification.

5.5.1 By BESC.

BESC will indemnify each Holder, each of its officers, directors and partners,
legal counsel and accountants and each person controlling such Holder within the
meaning of Section 15 of the Securities Act, with respect to which registration,
qualification or compliance has been effected pursuant to this Article V, and
each underwriter, if any, and each person who controls within the meaning of
Section 15 of the Securities Act any underwriter, against all expenses, claims,
losses, damages and liabilities (or actions, proceedings or settlements in
respect thereof) arising out of or based on any untrue statement (or alleged
untrue statement) of a material fact contained in any prospectus, offering
circular or other document (including any related registration statement,
notification or the like) incident to any such registration, qualification or
compliance, or based on any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, or any violation by BESC of the Securities Act or any
rule or regulation thereunder applicable to BESC and relating to action or
inaction required of BESC in connection with any such registration,
qualification or compliance, and will reimburse each such Holder, each of its
officers, directors, partners, legal counsel and accountants and each person
controlling such Holder, each such underwriter and each person who controls any
such underwriter, for any legal and any other expenses reasonably incurred in
connection with investigating and defending or settling any such claim, loss,
damage, liability or action, provided that BESC will not be liable in any such
case to the extent that any such claim, loss, damage, liability or expense
arises out of or is based on any untrue statement or omission based upon written
information furnished to BESC by such Holder or underwriter and stated to be
specifically for use therein. It is agreed that the indemnity agreement
contained in this Section 5.5.1 shall not apply to amounts paid in settlement of
any such loss, claim, damage, liability or action if such settlement is effected
without the consent of BESC (which consent has not been unreasonably withheld).

5.5.2 By the Holders.

Each Holder (other than the University of Maryland, Baltimore) will, if
Registrable Securities held by him are included in the securities as to which
such registration, qualification or compliance is being effected, indemnify
BESC, each of its directors, officers, partners, legal counsel and accountants
and each underwriter, if any, of the BESC's securities covered by such a
registration statement, each person who controls BESC or such underwriter within
the meaning of Section 15 of the Securities Act, each other such Holder and
Other Stockholder and each of their officers, directors and partners, and each
person controlling such Holder or Other Stockholder, against all claims, losses,
damages and liabilities (or actions in respect thereof) arising out of or based
on any untrue statement (or alleged untrue statement) of a material fact
contained in any such registration statement, prospectus, offering circular or

                                       34
<PAGE>

other document, or any omission (or alleged omission) to state therein a
material fact required to be stated therein or necessary to make the statements
therein not misleading, and will reimburse BESC and such Holders, Other
Stockholders, directors, officers, partners, legal counsel and accountants,
persons, underwriters or control persons for any legal or any other expenses
reasonably incurred in connection with investigating or defending any such
claim, loss, damage, liability or action, in each case to the extent, but only
to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in such registration statement,
prospectus, offering circular or other document in reliance upon and in
conformity with written information furnished to BESC by such Holder; provided,
however, that the obligations of such Holder hereunder shall not apply to
amounts paid in settlement of any such claims, losses, damages or liabilities
(or actions in respect thereof) if such settlement is effected without the
consent of such Holder (which consent shall not be unreasonably withheld).
Notwithstanding anything contained herein to the contrary, the foregoing
indemnification, hold harmless, and reimbursement obligations shall not apply to
the University of Maryland, Baltimore.

5.5.3 Notice.

Each party entitled to indemnification under this Section 5.5 (the "Indemnified
Party") shall give notice to the party required to provide indemnification (the
"Indemnifying Party") promptly after such Indemnified Party has actual knowledge
of any claim as to which indemnity may be sought, and shall permit the
Indemnifying Party to assume the defense of any such claim or any litigation
resulting therefrom, provided that counsel for the Indemnifying Party, who shall
conduct the defense of such claim or any litigation resulting therefrom, shall
be approved by the Indemnified Party (whose approval shall not unreasonably be
withheld), and the Indemnified Party may participate in such defense at such
party's expense, and provided further that the failure of any Indemnified Party
to give notice as provided herein shall not relieve the Indemnifying Party of
its obligations under this Section 5.5, to the extent such failure is not
prejudicial. No Indemnifying Party, in the defense of any such claim or
litigation, shall, except with the consent of each Indemnified Party, consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party of a release from all liability in respect to such claim or
litigation. Each Indemnified Party shall furnish such information regarding
itself or the claim in question as an Indemnifying Party may reasonably request
in writing and as shall be reasonably required in connection with defense of
such claim and litigation resulting therefrom.

5.5.4 Contribution.

If the indemnification provided for in this Section 5.5 is held by a court of
competent jurisdiction to be unavailable to an Indemnified Party with respect to
any loss, liability, claim, damage or expense referred to therein, then the
Indemnifying Party, in lieu of indemnifying such Indemnified Party hereunder,
shall contribute to the amount paid or payable by such Indemnified Party as a
result of such loss, liability, claim, damage or expense in such proportion as

                                       35
<PAGE>

is appropriate to reflect the relative fault of the Indemnifying Party on the
one hand and of the Indemnified Party on the other in connection with the
statements or omissions which resulted in such loss, liability, claim, damage or
expense as well as any other relevant equitable considerations. The relative
fault of the Indemnifying Party and of the Indemnified Party shall be determined
by reference to, among other things, whether the untrue or alleged untrue
statement of a material fact or the omission to state a material fact relates to
information supplied by the Indemnifying Party or by the Indemnified Party and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission.

5.5.5 Underwriting Agreement to Control.

Notwithstanding the foregoing, to the extent that the provisions on
indemnification and contribution contained in the underwriting agreement entered
into in connection with the underwritten public offering are in conflict with
the foregoing provisions, the provisions in the underwriting agreement shall
control.

5.5.6 Information by Holder.

Each Holder of Registrable Securities shall furnish to BESC such information
regarding such Holder and the distribution proposed by such Holder as BESC may
reasonably request in writing and as shall be reasonably required in connection
with any registration, qualification or compliance referred to in this Article
V.

5.6 Rule 144 Reporting.

With a view to making available the benefits of certain rules and regulations of
the Commission which may permit the sale of the Restricted Securities to the
public without registration, BESC agrees to use its best efforts to:

     (a) Make and keep public information available as those terms are
     understood and defined in Rule 144 under the Securities Act;

     (b) File with the Commission in a timely manner all reports and other
     documents required of BESC under the Securities Act and the Exchange Act at
     any time after it has become subject to such reporting requirements;

     (c) So long as a Holder owns any Restricted Securities, furnish to the
     Holder forthwith upon written request a written statement by BESC as to its
     compliance with the reporting requirements of Rule 144, a copy of the most
     recent annual or quarterly report of the Company, and such other reports
     and documents so filed as a Holder may reasonably request in availing
     itself of any rule or regulation of the Commission allowing a Holder to
     sell any such securities without registration.

5.7 Transfer or Assignment of Registration Rights.

The rights to cause BESC to register securities granted to a Holder by BESC
under Section 5.2, may be transferred or assigned by a Holder only to a
transferee or assignee of not less than 100,000 shares of Registrable Securities
(as presently constituted and subject to subsequent adjustments for stock
splits, stock dividends, reverse stock splits and the like), and only provided
that BESC is given written notice at the time of or within a reasonable time
after said transfer or assignment, stating the name and address of said

                                       36
<PAGE>

transferee or assignee and identifying the securities with respect to which such
registration rights are being transferred or assigned, and provided further that
the transferee or assignee of such rights assumes the obligations of such Holder
under this Article V.

5.8 Allocation of Registration Opportunities.

In any circumstance in which all of the Registrable Securities and other shares
of Common Stock of BESC (including shares of Common Stock issued or issuable
upon conversion of shares of any currently unissued series of Preferred Stock of
the Company) with registration rights (the "Other Shares") requested to be
included in a registration on behalf of the Holders or other selling
stockholders cannot be so included as a result of limitations of the aggregate
number of shares of Registrable Securities and Other Shares which may be so
included, the number of shares of Registrable Securities and Other Shares which
may be so allocated among the Holders and other selling stockholders requesting
inclusion of shares pro rata on the basis of the number of shares of Registrable
Securities and Other Shares that would be held by such Holders and other selling
stockholders, assuming conversion; provided, however, that, so that such
allocation shall not operate to reduce the aggregate number of Registrable
Securities and Other Shares to be included in such registration, if any Holder
or other selling stockholder does not request inclusion of the maximum number of
shares of Registrable Securities and Other Shares allocated to him pursuant to
the above-described procedure, the remaining portion of his allocation shall be
reallocated among those requesting Holders and other selling stockholders whose
allocations did not satisfy their requests pro rata on the basis of the number
of shares of Registrable Securities and Other Shares that would be held by such
Holders and other selling stockholders, assuming conversion, and this procedure
shall be repeated until all of the shares of Registrable Securities and Other
Shares that may be included in the registration on behalf of the Holders and
other selling stockholders have been so allocated. BESC shall not limit the
number of Registrable Securities to be included in a registration pursuant to
this Agreement in order to include shares held by stockholders with no
registration rights or to include any other shares of stock issued to employees,
officers, directors or consultants pursuant to BESC's Employee Stock Option
Plan, or with respect to registrations under Section 5.2, in order to include in
such registration securities registered for the Company's own account.

5.9 Delay of Registration.

No Holder shall have any right to take and, action to restrain, enjoin, or
otherwise delay any registration as the result of any controversy that might
arise with respect to the interpretation or implementation of this Article V.

except such information as is or becomes (a) available to the non-disclosing
party from third parties not subject to an undertaking of confidentiality or
secrecy; (b) generally available to the public other than as a result of a

prior to release, provided that such approval shall not be unnecessarily
withheld, subject, in the case of BESC, to BESC's obligation to comply with
applicable securities laws.

6.7 Consents.

BESC and JDA shall each promptly apply for or otherwise seek, and use its best
efforts to obtain, all consents and approvals required to be obtained by it for

order or authorization of, or any registration, declaration or filing with, any
Governmental Entity or other person, required to be obtained or made in

foregoing obligations shall not be construed to require JDA to pay money or
other consideration to stockholders of JDA to unduly influence such stockholders
to vote in favor of the Merger and the transactions contemplated hereby.

BESC shall take such steps as may be necessary to comply with the securities and
blue-sky laws of all jurisdictions which are applicable to the issuance of BESC

9.7 Interpretation.

When a reference is made in this Agreement to Schedules or Exhibits, such
reference shall be to a Schedule or Exhibit to this Agreement unless otherwise
indicated. The words "include," "includes" and "including" when used herein
shall be deemed in each case to be followed by the words "without limitation".
The table of contents and headings contained in this Agreement are for reference
purposes only and shall not affect in any way the meaning or interpretation of
this Agreement.

9.8 Counterparts.

This Agreement may be executed in one or more counterparts, all of which shall
be considered one and the same agreement and shall become effective when one or
more counterparts have been signed by each of the parties and delivered to the
other party, it being understood that all parties need not sign the same
counterpart.

9.9 Entire Agreement.

This Agreement and the documents and instruments and other agreements among the
parties hereto (a) constitute the entire agreement among the parties with
respect to the subject matter hereof and supersede all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter hereof; (b) are not intended to confer upon any other person any
rights or remedies hereunder; and (c) shall not be assigned by operation of law
or otherwise except as otherwise agreed in writing.

9.10 Governing Law.

This Agreement shall be governed in all respects, including validity,
interpretation and effect, by the laws of the State of Arizona. All parties
hereto agree to submit to the jurisdiction of the federal and state courts of
the State of Arizona.

9.11 Attorneys' Fees.

Subject to the provisions of Section 9.10 which shall govern the awarding of
attorneys' fees in any arbitration conducted pursuant to Section 9.10, if any
party to this Agreement brings an action against another party to this Agreement
to enforce its rights under this Agreement, the prevailing party shall be
entitled to recover its reasonable costs and expenses, including reasonable
attorneys' fees and costs, incurred in connection with such action, including
any appeal of such action.

9.12 Disputes.

Any dispute, disagreement, claim or controversy arising out of or relating to
this Agreement, any document or instrument delivered pursuant to, in connection
with, or simultaneously with this Agreement, or any breach of this Agreement

good faith negotiation before resorting to any legal proceedings or any other

                                       46

dispute resolution procedure. If the Dispute cannot be settled through
negotiation, the parties shall make every reasonable effort to settle the
Dispute by mediation by a single mediator qualified to consider the matter in
dispute before resorting to any legal proceedings or any other dispute
resolution procedure. If a Dispute cannot be settled through mediation, the
Dispute shall be finally settled by arbitration to be held in Phoenix, Arizona,
under the Rules of Commercial Arbitration of the American Arbitration
Association by a panel of three (3) arbitrators qualified to consider the matter
in dispute. The arbitrators may grant injunctions or other relief in such
dispute or controversy. The decision of a majority of the arbitrators shall be
final, conclusive and binding upon the parties to the arbitration; and any party
shall be entitled to cause judgment on the decision or award of the arbitrators
to be entered in any court of competent jurisdiction. Any party may initiate a
mediation or an arbitration by providing written notice of the mediation or
arbitration, as the case may be (the "Dispute Notice"), to the other parties,
which Dispute Notice shall state the name of initiating party, briefly state the
matter to be mediated or arbitrated, and, if applicable, name a person whom such
party has nominated to act as mediator. If, within thirty (30) days after the
date of the Dispute Notice, the parties have not agreed among themselves as to
the identity of the mediator, then any party may immediately refer this matter
for resolution by the American Arbitration Association. The parties shall each
pay their pro rata share (according to the number of parties involved in the
Dispute) of the costs, deposits and expenses of the mediator. The party
initiating the arbitration shall pay the costs, deposits and expenses of such
arbitration and the prevailing party shall be awarded its attorneys' fees and
expenses in addition to all other relief awarded by the arbitrators, provided
that if the arbitrators determine that a party has initiated an arbitration
without a reasonable basis for doing so, then the arbitrators shall assess
against that party all costs relating to the arbitration, including the
attorneys' fees and expenses of the other parties.

9.13 Rules of Construction.

The parties hereto agree that they have been represented by counsel during the
negotiation and execution of this Agreement and, therefore, waive the
application of any law, regulation, holding or rule of construction providing
that ambiguities in an agreement or other document will be construed against the
party drafting such agreement or document.
