     (a) constitute transactions exempt from the registration requirements of
Section 5 of the Securities Act, and the qualification or registration
requirements of any applicable state securities laws as such laws exist on the
date hereof; and

     (b) constitute transactions exempt from prospectus and registration
requirements of the Securities Act (British Columbia) and the securities
legislation of each other province of Canada in which Purchaser resides.

     4. Representations and Warranties of Purchaser and Restrictions on Transfer
Imposed by the Securities Act and Applicable State Securities Laws.

     4.1 Representations and Warranties by Purchaser. Purchaser represents and
warrants to the Company as follows:

     (a) The Class A Preferred Shares and the Conversion Shares (collectively,
the "Securities") are being or will be acquired for Purchaser's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Securities
Act, or applicable state securities laws.

     (b) Purchaser understands that (i) the Securities have not been registered
under the U.S. Securities Act of 1933, as amended (the "Securities Act") by
reason of their issuance in a transaction exempt from the registration and
prospectus delivery requirements of the Securities Act pursuant to Section 4(2)
thereof and have not been qualified under any U.S. state securities laws on the
grounds that the offering and sale of securities contemplated by this Agreement
are exempt from registration thereunder, and (ii) the Company's reliance on such
exemptions is predicated on Purchaser's representations set forth herein.
Purchaser understands that the resale of the Securities may be restricted
indefinitely, unless a subsequent disposition thereof is registered under the
Securities Act and registered under any state securities law or is exempt from
such registration in the United States or a prospectus is filed and receipted
with applicable securities regulatory authorities of the provinces of Canada.

     (c) Purchaser is an "accredited investor" within the meaning of Rule 501 of
Regulation D under the Securities Act, as presently in effect, and has been
advised that Class A Preferred Shares have not been registered and, therefore,
will be subject to restrictions on transfer pursuant to applicable securities
laws. Purchaser is a resident in the jurisdiction set forth below their
respective name in the signature page hereto. Purchaser has not been formed
solely for the purpose of making this investment and is purchasing the Class A
Preferred Shares to be acquired by Purchaser hereunder as principal for its own
account for investment, not as a nominee or agent, and not with a view to, or
for resale in connection with, the distribution thereof. Purchaser has such
knowledge and experience in financial and business matters that Purchaser is
capable of evaluating the merits and risks of such investment, is able to incur
a complete loss of such investment and is able to bear the economic risk of such
investment for an indefinite period of time.

     (d) Purchaser is aware of the provisions of Rule 144 promulgated under the
Securities Act which permit limited resale of shares purchased in a private
placement subject to the satisfaction of certain conditions, including, among
other things, the existence of a public market for the shares of the Company's
capital stock, the availability of certain current public information about the
Company, the resale occurring not less than one year after a party has purchased
and paid for the security to be sold, the sale being effected through a
"broker's transaction" or in a transaction directly with a "market maker," and
the number of shares being sold during any three-month period not exceeding
specified limitations. Purchaser further understands that there is no assurance
that Rule 144 or any exemption from the Securities Act will be available, or if
available, that such exemption will allow Purchaser to dispose of or otherwise
transfer any or all of the Shares or the Conversion Stock under the
circumstances, in the amounts or at the times Purchaser might propose.

     (e) During the negotiation of the transactions contemplated herein, the
Purchaser and its representatives and legal counsel have been afforded access to
corporate books, financial statements, records, contracts, documents, and other
information concerning the Company and to its offices and facilities, have been
afforded an opportunity to ask such questions of the Company's officers,
employees, agents, accountants and representatives concerning the Company's
business, operations, financial condition, assets, liabilities and other
relevant matters as they have deemed necessary or desirable, and have been given
all such information as has been requested, to evaluate the merits and risks of
the prospective investments contemplated herein.

     (f) Purchaser has the full right, power and authority to enter into and
perform Purchaser's obligations under this Agreement and the Investor Rights
Agreement, and this Agreement and the Investor Rights Agreement constitutes
valid and binding obligations of Purchaser enforceable in accordance with their
terms.

     (g) No consent, approval or authorization of or designation, declaration or
filing with any Governmental Body on the part of Purchaser is required in
connection with the valid execution and delivery of this Agreement or the
Investor Rights Agreement.

     4.2 Legend. Each certificate representing the Securities may be endorsed
with the following legends:

     (a) THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED
UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), AND ARE "RESTRICTED
SECURITIES" AS DEFINED IN RULE 144 PROMULGATED UNDER THE ACT. THE SECURITIES MAY
NOT BE SOLD OR OFFERED FOR SALE OR OTHERWISE DISTRIBUTED EXCEPT (I) IN
CONJUNCTION WITH AN EFFECTIVE REGISTRATION STATEMENT FOR THE SHARES UNDER THE
ACT OR (II) IN COMPLIANCE WITH RULE 144 OR (III) OTHERWISE PURSUANT TO AN
EXEMPTION FROM THE REGISTRATION REQUIREMENTS UNDER THE ACT BASED ON AN OPINION
OF COUNSEL REASONABLY SATISFACTORY TO THE ISSUER;

     (b) UNLESS PERMITTED UNDER SECURITIES LEGISLATION, THE HOLDER OF THIS
SECURITY MUST NOT TRADE THE SECURITY BEFORE THE DATE THAT IS FOUR MONTHS AND A
DAY AFTER THE LATER OF (i) JUNE __, 2005 AND (ii) THE DATE THE ISSUER BECAME A
REPORTING ISSUER IN ANY PROVINCE OR TERRITORY OF CANADA; and

     (c) Any other legends required by applicable securities laws or the
Investor Rights Agreement.

     The Company may instruct its transfer agent not to register the transfer of
the Securities, unless the conditions specified in the foregoing legends are
satisfied. 4.3 Removal of Legend and Transfer Restrictions. (a) Any legend
endorsed on a certificate pursuant to Section 4.2(a) and the stop transfer
instructions with respect to such Securities shall be removed and the Company
shall issue a certificate without such legend to the holder thereof (1) if such
Securities are registered under the Securities Act and a prospectus meeting the
requirements of Section 10 of the Securities Act is available, (2) if such
legend may be properly removed under the terms of Rule 144 promulgated under the
Securities Act, or (3) if such holder provides the Company with an opinion of
counsel for such holder, reasonably satisfactory to legal counsel for the
Company to the effect that a sale, transfer or assignment of such Securities may
be made without registration.

     (b) Any legend endorsed on a certificate pursuant to Section 4.2(b) and the
stop transfer instructions with respect to such Securities as it applies to
Section 4.2(b) shall be removed and the Company shall issue a certificate
without such legend to the holder thereof if (i) a receipt is obtained for a
prospectus in all applicable provinces qualifying the Securities; or (ii) the
Company becomes a reporting issuer in all applicable Canadian provinces and the
hold period applicable to the Securities under applicable provincial securities
laws has expired.

     5. Indemnity.

     5.1 Survival. The representations and warranties of the parties contained
in this Agreement shall survive the Closing indefinitely.

     5.2 Indemnity.

     (a) The Company hereby agrees to indemnify and defend and hold harmless the
Purchaser, its Affiliates, successors and assigns and each of their respective
officers, directors, employees and agents (the "Indemnified Parties") from and
against, and agrees to pay or cause to be paid to the Indemnified Parties all
amounts equal to the sum of, any and all claims, demands, costs, expenses,
losses and other liabilities of any kind that the Indemnified Parties may incur
or suffer (including without limitation all reasonable legal fees and expenses)
which arise or result from any breach of or failure by the Company to perform
any of its representations, warranties, covenants or agreements in this
Agreement or the Investor Rights Agreement; provided, however, such
indemnification shall not include payment of consequential damages of the
Indemnified Parties. The rights of Purchaser hereunder shall be in addition to,
and not in lieu of, any other rights and remedies which may be available to them
by law.

     5.3 Procedures.

     (a) If a third party shall notify an Indemnified Party with respect to any
matter that may give rise to a claim for indemnification under the indemnity set
forth above in Section 5.2, the procedure set forth below shall be followed.

     (i) Notice. The Indemnified Party shall give to the party providing
indemnification (the "Indemnifying Party") written notice of any claim, suit,
judgment or matter for which indemnity may be sought under Section 5.2 promptly
but in any event within thirty days after the Indemnified Party receives notice
thereof; provided, however, that failure by the Indemnified Party to give such
notice shall not relieve the Indemnifying Party from any liability it shall
otherwise have pursuant to this Agreement except to the extent that the
Indemnifying Party is actually prejudiced by such failure. Such notice shall set
forth in reasonable detail (i) the basis for such potential claim and (ii) the
dollar amount of such claim. The Indemnifying Party shall have a period of
fifteen days within which to respond to the Indemnified Party thereto regarding
acceptance or rejection of the Indemnified Party's claim (the "Response"). If
the Indemnifying Party does not issue a Response within such fifteen-day period,
the Indemnifying Party shall be deemed to have accepted responsibility for such
indemnity.

     (ii) Defense of Claim. With respect to a claim by a third party against an
Indemnified Party for which indemnification may be sought under this Agreement,
the Indemnifying Party shall have the right, at its option, to be represented by
counsel of its choice and to assume the defense or otherwise control the
handling of any claim, suit, judgment or matter for which indemnity is sought,
which is set forth in the notice sent by the Indemnified Party, by notifying the
Indemnified Party in its Response; provided, however, that the Indemnified Party
shall have the right to employ counsel to represent it if, in the Indemnified
Party's reasonable judgment based upon the advice of counsel, it is advisable in
light of the separate interests of the Indemnified Party, to be represented by
separate counsel, and in that event the reasonable fees and expenses of such
separate counsel shall be paid by the Indemnifying Party. If the Indemnifying
Party does not give timely notice in its Response in accordance with the
preceding sentence, the Indemnifying Party shall be deemed to have given notice
that it does not wish to control the handling of such claim, suit or judgment.
In the event the Indemnifying Party elects (by notice in writing within such
fifteen-day period) to assume the defense of or otherwise control the handling
of any such claim, suit, judgment or matter for which indemnity is sought, the
Indemnifying Party shall indemnify and hold harmless the Indemnified Party from
and against any and all reasonable professional fees (including attorneys' fees,
accountants, consultants and engineering fees) and investigation expenses
incurred by the Indemnifying Party prior to such election, notwithstanding the
fact that the Indemnifying Party may not have been so liable to the Indemnified
Party had the Indemnifying Party not elected to assume the defense of or to
otherwise control the handling of such claim, suit, judgment or other matter. In
the event that the Indemnifying Party does not assume the defense or otherwise
control the handling of such matter, the Indemnified Party may retain counsel,
as an indemnification expense, to defend such claim, suit, judgment or matter.

     (iii) Final Authority. The parties shall cooperate in the defense of any
such claim or litigation and each shall make available all books and records
which are relevant in connection with such claim or litigation. In connection
with any claim, suit or other proceeding with respect to which the Indemnifying
Party has assumed the defense or control, the Indemnifying Party will not
consent to the entry of any judgment or enter into any settlement with respect
to any matter which does not include a provision whereby the plaintiff or
claimant in the matter releases the Indemnified Party from all liability with
respect thereto, without the written consent of the Indemnified Party. In
connection with any claim, suit or other proceeding with respect to which the
Indemnifying Party has not assumed the defense or control, the Indemnified Party
may not compromise or settle such claim without the consent of the Indemnifying
Party, which shall not be unreasonably withheld and shall be deemed to have been
given if the Indemnified Party provides the Indemnifying Party with a written
notice setting forth the material terms of such compromise or settlement and the
Indemnifying Party does not object thereto in writing within ten days of its
receipt of such notice.

     (b) Claims Between the Indemnifying Party and the Indemnified Party. Any
claim for indemnification under this Agreement which does not result from the
assertion of a claim by a third party shall be asserted by written notice given
by the Indemnified Party to the Indemnifying Party. The Indemnifying Party shall
have a period of thirty days within which to respond thereto.

     6. Covenants.

     6.1 Insurance. The Company shall maintain insurance, including but not
limited to Director's and Officer's Insurance, with responsible and reputable
insurance companies or associations in such amounts and covering such risks as

similar properties in the same general areas in which the Company operates. The
Company shall pay all such insurance premiums payable by them.

     6.2 Compliance with Laws. The Company shall comply with the requirements of
all applicable laws, rules, regulations and orders of any governmental
authority, non-compliance with which could have a Material Adverse Effect.

     6.3 Expenses of Directors. The Company shall reimburse any directors
designated by the Purchaser to the Board of Directors for all reasonable
expenses incurred by any such director in connection with the carrying out of
such director's duties to the Company, including without limitation travel,
entertainment, meals, lodging and related expenses in connection with such
directors' attendance at meetings of the Company's Board of Directors or
committees thereof.

     6.4 Tax Matters. The Company shall, and shall cause each of its
subsidiaries to: (i) prepare and timely file, or cause to be prepared and timely
filed, all tax returns and reports required to be filed by it, each in the
manner required by applicable law in all material respects and in a manner that
is accurate and complete in all material respects, and (ii) pay all income,
sales, use, occupation, property and other taxes and assessments that are due in
accordance with applicable law, on or before the due date therefor, whether or
not such taxes or assessments are shown on any such tax return.

the proceeds received by it from the issuance and sale of the Class A Preferred
Shares shall be used for product development, corporate infrastructure and
working capital.

     6.6 Unwind. In the event that (a) the Arrangement is terminated for any
reason or (b) the Arrangement is not consummated within fifty weeks after the
date of this Agreement, then the Purchaser and Perseus 2000 Expansion shall take
the actions set forth in Section 2.1(f) of the Investment Agreement, dated as of
April 22, 2005, by and between Perseus 2000 Expansion and the Purchaser.

     6.7 Investor Rights Agreement. The Company hereby covenants that the
Purchaser shall have the right to execute a joinder agreement to the Investor
Rights Agreement. The Company hereby further covenants and agrees that it shall
use its respective best efforts to have the other parties to the Investor Rights
Agreement acknowledge the Purchaser's rights thereunder. Notwithstanding the
foregoing, in the event that the actions set forth in Section 6.6 hereof result
in the Purchaser exchanging its Shares with Perseus 2000 Expansion, the
Purchaser shall take such further actions reasonably requested by the Company to
acknowledge and confirm the termination of its rights pursuant to the Investor
Rights Agreement.

     7. Miscellaneous.

     7.1 Waivers and Amendments. This Agreement may not be amended except
pursuant to an agreement in writing executed by the Company and Purchaser;
provided that Section 1.2(b) of this Agreement shall not be amended without the

the other exhibits hereto and thereto constitute the full and entire

     7.7 Severability. In case any provision of this Agreement shall be declared
invalid, illegal or unenforceable, the validity, legality and enforceability of
the remaining provisions shall not in any way be affected or impaired thereby.

     7.8 Titles and Subtitles. The titles of the paragraphs and subparagraphs of
this Agreement are for convenience of reference only and are not to be

disclosure is required by applicable law, provided, however, within sixty (60)
days of the date of this Agreement, the Company may issue a press release
disclosing that Purchaser has invested in the Company, provided that the final

     7.11 No Strict Construction. The parties hereto have participated jointly
in the negotiation and drafting of this Agreement. In the event an ambiguity or
question of intent or interpretation arises, this Agreement shall be construed
as if drafted jointly by the parties hereto, and no presumption or burden of
proof shall arise favoring or disfavoring any party by virtue of the authorship
of any of the provisions of this Agreement.

                [Farris, Vaughan, Wills & Murphy LLP Letterhead]

                                                             July ___, 2005

  TO: Beacon Power Corporation

  Dear Sirs:

                  Re:      NxtPhase T & D Corporation

We have acted as counsel to NxtPhase T & D Corporation (the "Corporation") in
connection with the issuance and sale by the Corporation of 111,111 Class A
Preferred Shares (the "Class A Preferred Shares") for US $4.50 per share, in
accordance with the terms of a securities purchase agreement (the "Securities
Purchase Agreement"), dated July , 2005, between the Corporation and Beacon
Power Corporation (the "Investor").

This opinion is being provided pursuant to section 2.3(a)(v) of the Securities
Purchase Agreement and, unless the context requires otherwise, all capitalized
terms not otherwise defined herein shall have the meanings ascribed thereto in
the Securities Purchase Agreement.

SCOPE OF INQUIRIES

We have examined the following documents:

Incorporation and By-laws of the Corporation; and (c) Resolutions of the
Directors of the Corporation.

We have also examined such corporate records of the Corporation, certificates of
public officials, certificates of officers of the Corporation, and other
documents and have made such other searches and examinations and considered such
questions of law as we have considered necessary in order to give the opinions
expressed below.

ASSUMPTIONS

     (d) that each party to any agreement or instrument referred to herein,
other than the Corporation, has all necessary power and authority to execute and
deliver such agreement or instrument and to do all acts and things as required
or contemplated to be done thereby, has duly authorized the execution and
delivery of such agreement or instrument and the observance and performance of
its obligations thereunder, has duly executed such agreement or instrument and
has duly delivered the same to each of the other parties thereto;

     (e) that to the extent any of the matters as to which we opine are governed
by any laws other than those of the Province of British Columbia or the federal
laws of Canada applicable therein we have assumed with your permission, without
independent investigation or verification, that (i) such laws are identical in
all respects to the laws of the Province of British Columbia and the federal
laws of Canada applicable therein;

     (f) that the Securities Purchase Agreement constitutes legal, valid and
binding obligations of all parties thereto, enforceable in accordance with its
terms under the laws of the jurisdiction expressly chosen by the parties to
govern the such document, being the laws of the State of New York;

     (g) if any obligation under any of the Securities Purchase Agreement falls
to be performed in any jurisdiction outside of the Province of British Columbia,

of the laws of that jurisdiction;

     (h) that the acknowledgements, representations and warranties of the
parties to the Securities Purchase Agreement, other than those of the
Corporation, are true, correct and accurate in all respects; and

     (i) the accuracy and completeness of all information provided to us (in
written form or by facsimile transmission) by offices of public record.

RELIANCE

In expressing the opinion set forth in paragraph 1 below, we have relied solely
upon a Certificate of Compliance issued in respect of the Corporation by the
Deputy Director under the Canada Business Corporations Act, dated July , 2005.

In expressing the opinions set forth below, we have relied as to matters of fact
solely upon certificates of an officer of the Corporation, copies of which have
been delivered to you concurrently herewith, with respect to the accuracy of
factual matters contained therein.

OPINION

We express no opinion as to any laws, or matters governed by any laws other than
the laws of the Province of British Columbia and the federal laws of Canada
applicable therein.

The expressions "to our knowledge" or "of which we have knowledge", when used
herein, means to the actual knowledge of the partners and associates of our firm
who have had involvement with the matters contemplated in this opinion.

Based and relying on the foregoing, and subject to the qualifications set out
below, we are of the opinion that:

1.   The Corporation is a corporation duly incorporated and validly existing
     under the Canada Business Corporations Act and is in good standing with
     respect to the filing of annual returns.

2.   The Corporation has the corporate power and capacity to (a) own, lease and
     operate its properties and conduct its business as, to our knowledge, it is
     currently conducted and (b) to execute, deliver and perform its obligations
     under the Securities Purchase Agreement.

3.   The authorized share capital of the Corporation consists of an unlimited
     number of Common Shares and an unlimited number of Class A Preferred
     Shares, of which, on the date hereof prior to the issuance of the Class A
     Preferred Shares contemplated in the Securities Purchase Agreement,
     1,000,000 Common Shares and 1,659,829 Class A Preferred Shares are validly
     issued and outstanding as fully paid and non-assessable shares in the
     capital of the Corporation. The Class A Preferred Shares have the rights,
     preferences, restrictions and privileges set forth in the Corporation's
     Articles of Incorporation.

4.   The execution and delivery by the Corporation of the Securities Purchase
     Agreement and the consummation by the Corporation of the transactions
     contemplated thereby, have been duly authorized by all necessary
     corporation action on the part of the Corporation and the Securities
     Purchase Agreement has been duly executed and delivered by the Corporation
     and constitutes a legal, valid and binding obligation of the Corporation
     enforceable against the Corporation in accordance with its terms.

5.   The choice of the laws of the State of New York to govern the Securities
     Purchase Agreement will be upheld as a valid choice of law by the courts of
     the Province of British Columbia provided that the choice of law is bona
     fide (in that it was not made with a view to avoiding the consequences of
     the law of any other jurisdiction) and is not contrary to public policy, as
     that term is understood under the laws of the Province of British Columbia;
     in an action brought before a court of competent jurisdiction in the
     Province of British Columbia in respect of the Securities Purchase
     Agreement, the laws of the State of New York, to the extent specifically
     pleaded and proved as a matter of a fact by expert evidence, would be
     recognized and applied by such courts to all issues that, under the
     conflict of laws rules of the Province of British Columbia, are to be
     determined in accordance with the proper or governing law of the Securities
     Purchase Agreement if the choice of law in such document is valid; although
     the parties may have made a valid choice of law, the courts of the Province
     of British Columbia will not apply those laws: (i) which it characterizes
     as being of a revenue, penal or public law nature, (ii) which relate to
     matters of a procedural nature, or (iii) the application of which would be
     inconsistent with public policy, as that term is applied by the courts in
     the Province of British Columbia; in addition, a court of competent
     jurisdiction in British Columbia may reserve to itself an inherent power to
     decline to hear any such action if it is contrary to public policy for it
     to do so, or if it is not the proper forum to hear such an action, or if
     concurrent proceedings in respect of such matter are being brought
     elsewhere.

6.   The execution, delivery and performance by the Corporation of the
     Securities Purchase Agreement to which it is a party do not (i) violate the
     laws of the Province of British Columbia or any federal laws of Canada
     applicable therein, or any court order, judgment or decree which has been
     entered against the Corporation or any Subsidiary of which we have
     knowledge, (ii) constitute a default under or breach of, or result in the
     creation of a lien or a right of acceleration under, any of the agreements
     or instruments listed in Exhibit D or (iii) violate its Certificate and
     Articles of Incorporation or Bylaws.

7.   The Common Shares issuable upon conversion of the Class A Preferred Shares
     have been duly authorized and reserved for issuance upon conversion of the
     Class A Preferred Shares. The Class A Preferred Shares, when issued, sold
     and delivered against payment therefor in accordance with the provisions of
     the Securities Purchase Agreement, will be duly and validly issued, fully
     paid and non-assessable. The Common Shares, when issued upon conversion of
     the Class A Preferred Shares in accordance with their terms, will be duly
     and validly issued, fully paid and non-assessable.

8.   To our knowledge, there is no action, proceeding or litigation pending or
     threatened against the Corporation before any court or any governmental or
     administrative agency or body.

9.   No notices, reports or other filings are required to be made by the
     Corporation or any of its subsidiaries with, nor are any consents,
     registrations, applications, approvals, permits, licenses or authorizations
     required to be obtained by the Corporation from, securities regulatory
     authorities in the Province of British Columbia for the issuance of the
     Class A Preferred Shares or the issuance and delivery of the Common Shares
     upon conversion of the Class A Preferred Shares so long as no commission or
     other remuneration is paid or given to others in respect of the trade
     except for administrative or professional services or for services
     performed by a registered dealer, other than normal post-closing filings in
     connection with qualifying for exemptions from the prospectus and
     registration requirements of applicable securities laws.

10.  The offer and sale of the Class A Preferred Shares pursuant to the
     Securities Purchase Agreement are exempt from the prospectus and
     registration requirements of the Securities Act (British Columbia), subject
     to the Corporation filing a report with the British Columbia Securities
     Commission of such trade on or before the 10th day after the trade, on Form
     45-103F4, prepared and executed in accordance with the Securities Act
     (British Columbia), the rules and regulations made and promulgated
     thereunder and the instruments, policies, notices and interpretation notes
     of the British Columbia Securities Commission together with the requisite
     filing fee and a duly completed fee checklist.

QUALIFICATIONS

   The opinions expressed herein are subject to the following qualifications and
limitations:

1.   The enforceability of the obligations of the parties to the Securities
     Purchase Agreement and the rights and remedies set out therein and any
     judgment arising out of or in connection therewith are subject to and may
     be limited by:

     (a)  applicable bankruptcy, reorganization, arrangement, winding-up,
          insolvency, liquidation, moratorium, preference and other similar laws
          and judicial decisions from time to time in effect affecting the
          enforcement of rights and remedies of creditors;

     (b)  applicable laws regarding limitations of actions;

     (c)  the equitable and statutory powers of the courts to stay proceedings
          before them, to stay the execution of judgments, to limit the right of
          a creditor to receive immediate payment of amounts stated to be
          payable on demand, to relieve from penalties or the consequences of
          default, particularly if the default is minor or non-substantive, to
          refrain from enforcing non-competition or other restrictive covenants
          and to grant relief against forfeiture; and

     (d)  the general principles of equity, whether enforceability is considered
          in a proceeding in equity or at law, and no opinion is expressed as to
          the availability of any specific remedy that may be granted, imposed
          or rendered or as to the availability of the remedy of specific
          performance, injunctive relief or other equitable remedies in any
          particular instance;

2.   Provisions in the Securities Purchase Agreement providing for the recovery
     of fees and expenses from any person may be restricted by a court to a
     reasonable amount, and legal fees are subject to taxation;

3.   No opinion is expressed on:

     (a)  provisions of the Securities Purchase Agreement which:

          (i)  purport to directly or indirectly exclude unwritten variations,
               waivers or consents of, to or under the Securities Purchase
               Agreement or restrict their effect;

          (ii) purport to restrict the access to, or waive the benefit of, legal
               or equitable remedies or defences;

          (iii) purport to bind or affect, or confer a benefit upon, persons who
               are not parties to the Securities Purchase Agreement;

          (iv) purport to establish evidentiary standards, such as provisions
               stating that certain determinations, calculations, requests or
               certificates will be conclusive or binding;

          (v)  purport to waive or affect any rights to notices;

          (vi) purport to allow severance of an invalid, illegal or
               unenforceable provision, or restrict its effect;

          (vii) relate to any taxes, levies, duties, imposts or charges which
               may be imposed upon, or exigible in respect of, any of the
               matters contemplated by the Securities Purchase Agreement, and in
               particular, but without limitation, no opinion is expressed as to
               any withholding tax that may be imposed upon, or exigible or
               payable in respect of, any such transactions;

4.   The effectiveness of provisions which purport to relieve a person from a
     liability or duty otherwise owed may be limited by law, and provisions
     requiring indemnification or reimbursement of a person may not be enforced
     by a court, to the extent that they relate to or arise as a result of the
     failure of such person to have performed a duty (contractual or otherwise)
     or from the breach of contract, tort or other wrongful act of such person.

5.   The opinions in paragraph 9 and 10 are subject to the qualification that no
     effective order, ruling or decision is issued or granted by a court or
     regulatory or administrative body that has the effect of precluding or
     restricting the issue and delivery by the Corporation of any securities
     referred to in such paragraphs or restricting any trades of such securities
     and at the relevant time there is no such order affecting any person who
     engages in such a trade.

6.   Canadian courts will not give monetary judgment in any currency other than
     that of Canada and such judgment may be based on a rate of exchange in
     existence on a day other than the date of payment of such judgment.

7.   The rate of post-judgment interest applicable to any obligation under the
     Securities Purchase Agreement lies within the discretion of the court.

   This opinion may not be relied upon by any person or entity other than the
addressees hereof, their successors and their assigns of whom we have notice at
the time of the assignment, and this opinion may not be circulated, quoted or
otherwise referred to for any purpose other than in connection with the
transactions contemplated by the Securities Purchase Agreement, in each case,
without our prior written consent. We do not undertake to advise you or anyone
else of any changes in the opinions expressed herein resulting from changes in
law, changes in facts or any other matters that hereafter might occur that did
not exist on the date hereof.

Yours truly,

The Company is a party to a binding Term Sheet with Perseus 2000, L.L.C. dated

anticipated that such options would be granted to employees of the Company.

The Company has an option to enter into a Long-Term License Agreement with The
Texas A&M University System ("TAMUS"). Pursuant to section 3.04 of that
Long-Term License Agreement, TAMUS would be entitled to receive NxtPhase Common

ARTICLE 2.
     DEFERRAL ELECTION

The Executive shall make an initial
deferral election under this Agreement by filing a signed Deferral Election
Agreement with the Bank stating (i) the amount of Compensation to be
deferred, and (ii) the Fixed Distribution Date in accordance with Article 1.07
herein.  The Deferral Election Agreement

performance period.  The Executive may
not change the form of benefit payment provided in this Agreement.

date the distribution would have otherwise been made, and (iii) the
election to change the Fixed Distribution Date is made no less than twelve (12)
months prior to the scheduled Fixed Distribution Date.  Subsequent elections that accelerate the
Fixed Distribution Date or change the form of distribution are prohibited.  Any election to change the Fixed Distribution

election shall remain in force.

 

ARTICLE 3.
     409A ACCOUNT

time such amounts would have otherwise been paid to the Executive.

 

B.                                     Interest.

 

Interest on the account balance of the 409A Account
shall accrue at an annual rate, compounded quarterly, that is equal to the Wall
Street Journal Prime Rate as of the first business day of the calendar quarter for
each quarter the account balance of the 409A Account has a credit balance.  Interest shall be calculated quarterly and
posted to the 409A Account on a quarterly basis at the end of each quarter.  Interest for any partial period should be
calculated based on the actual number of days in the quarter.  Interest shall accrue on the account balance
of the 409A Account until such time the 409A Account has been completely
distributed.

 

3.02.                        Statement of Accounts.

 

The Bank shall provide to the Executive, within one
hundred twenty (120) days after each anniversary of this Agreement, a statement
setting forth the 409A Account balance.

 

3.03.                        Accounting Device Only.

 

The 409A Account is solely a device for measuring

Bank for the payment of benefits under this Agreement.  The benefits represent the Bank’s mere

in sixty (60) substantially equal monthly installments.  Payment of benefits shall commence on the
first day of the month following the Fixed Distribution Date.  If the Executive terminates service with the
Bank prior to that time or fails to specify the Fixed Distribution Date in
accordance with Article 1.07, payment shall commence on the first day of
the seventh month following the Distribution Date due to the Executive’s
termination of employment.

The Bank
shall pay the Executive a benefit equal to the 409A Account balance on the date
of a Change of Control, and interest accruing thereon, after the Distribution
Date in sixty (60) substantially equal monthly installments.  Payment of benefits shall commence on the
first day of the month following the date of a Change of Control.

 

4.03                           Hardship Distributions.

 

If the Executive suffers a Financial
Hardship, as hereinafter defined, the Executive may apply to the Bank for the
payment of all or any part of his 409A Account. 
The Bank shall consider the circumstances of the Financial Hardship and
the best interests of the Executive and his family, and shall have the right,
in its sole discretion, to allow a distribution of part or all
of the amount requested, or to refuse to allow any distribution.  Upon a finding of Financial Hardship, the Bank
shall make the appropriate payment to the Executive in respect of the Executive’s
409A Account.  In no event shall the
aggregate amount of the distribution exceed the amount determined by the Bank
to be necessary to alleviate the Executive’s Financial Hardship or the full
value of the Executive’s Account, if less (a Financial Hardship may be
considered to include any taxes resulting from the hardship distribution), and
which is not reasonably available from other resources of the Executive.  For purposes of this Article, the value of
the Executive’s 409A Account shall be determined as of the date of the Hardship
Distribution.  “Financial Hardship” means
(i) a severe Financial Hardship to the Executive resulting from an illness
or accident of the Executive or a dependent of the Executive (as defined in
Code section 152(a)), (ii) loss of the Executive’s property due to
casualty, or (iii) other similar extraordinary and unforeseeable
circumstances arising as a result of events beyond the control of the Executive,
as determined to exist by the Bank.

 

ARTICLE 5.      DEATH

5.01.                        Death Prior To The Fixed Distribution Date.

 

If the Executive dies prior to the Fixed Distribution
Date, if any, the Bank shall pay the Executive’s beneficiary a benefit equal
to the 409A Account balance on the Distribution Date, and interest accruing
thereon after the Distribution Date, in sixty (60) substantially equal monthly
installments.  Payment of benefits shall
commence on the first day of the month following the Distribution Date.

 

5.02.                        Death During Benefit Period.

 

If the Executive dies after benefit payments have
commenced under this Agreement but before receiving all such payments, the Bank
shall pay the remaining benefits to the Executive’s beneficiary at the same time
and in the same amounts it would have paid to the Executive had the Executive
survived.

 

ARTICLE 6.      BENEFICIARIES

 

6.01.                        Beneficiary Designations.

 

The Executive shall designate a beneficiary by filing
the Designation of Beneficiary form incorporated herein as Exhibit II with
the Bank.  The Executive may revoke or
modify the designation at any time by filing a new designation.  However, a new designation will only be
effective if signed by the Executive and accepted by the Bank during the
Executive’s lifetime.  The Executive’s
beneficiary designation shall be deemed automatically revoked if the
beneficiary predeceases the Executive, or if the Executive names a spouse as
beneficiary and the marriage is subsequently dissolved.  If the Executive dies without a valid
beneficiary designation, all payments shall be made to the Executive’s estate.

6.02.                        Facility of Payment.

 

If a benefit is payable to a minor, to a person
declared incompetent, or a to a person incapable of handling the disposition of
his or her property, the Bank may pay such benefit to the guardian, legal
representative or person having the care or custody of such minor, incompetent
person or incapable person.  The Bank may
require proof of incompetency, minority or guardianship as it may deem
appropriate prior to distribution of the benefit.  Such distribution shall completely discharge
the Bank from all liability with respect to such benefit.

 

ARTICLE 7.      CLAIMS AND
REVIEW PROCEDURES

 

7.01.                        Claims Procedure.

 

The Bank shall notify the Executive’s beneficiary in
writing, within thirty (30) days of his or her written application for
benefits, of his or her eligibility or noneligibility for benefits under the
Agreement.  If the Bank determines that
the beneficiary is not eligible for benefits or full benefits, the notice shall
set forth (i) the specific reasons for such denial, (ii) a specific
reference to the provisions of the Agreement on which the denial is based, (iii) a
description of any additional information or material necessary for the
claimant to perfect his or her claim, and a description of why it is needed,
and (iv) an explanation of the Agreement’s claims review procedure and
other appropriate information as to the steps to be taken if the beneficiary
wishes to have the claim reviewed.  If
the Bank determines that there are special circumstances requiring additional
time to make a decision, the Bank shall notify the beneficiary of the special
circumstances and the date by which a decision is expected to be made, and may
extend the time for up to an additional thirty (30) day period.

 

7.02.                        Review Procedure.

 

If the beneficiary is determined by the Bank not to be
eligible for benefits, or if the beneficiary believes that he or she is
entitled to greater or different benefits, the beneficiary shall have the
opportunity to have such claim reviewed by the Bank by filing a petition for
review with the Bank within thirty (30) days after receipt of the notice issued
by the Bank.  Said petition shall state
the specific reasons which the beneficiary believes entitle him or her to
benefits or to greater or different benefits. 
Within sixty (60) days after receipt by the Bank of the petition, the Bank
shall afford the beneficiary (and counsel, if any) an opportunity to present
his or her position to the Bank orally or in writing, and the beneficiary (or
counsel) shall have the right to review the pertinent documents.  The Bank shall notify the beneficiary of its
decision in writing no later than thirty (30) days after receipt of the
presentation of the position of the beneficiary or sixty (60) days after
receipt by the Bank of the petition of the beneficiary, stating specifically
the basis of its decision, written in a manner calculated to be understood by
the beneficiary and the specific provisions of the Agreement on which the
decision is based.

 

7.03.                        Benefits Required To Be Paid.

 

Section 7.01 and 7.02 of this Article 7
shall not be construed to relieve the Bank of its obligation to pay Executive
or Executive’s beneficiary the benefits provided by this Agreement.

 

ARTICLE 8.      AMENDMENTS
AND TERMINATION

 

This Agreement may be amended or terminated only by a written agreement

and the Executive.  Notwithstanding any
other provision of this Agreement to the contrary, the Bank may amend this
Agreement at any time, without the consent of the Executive, effective as of
any date, if the Bank determines in its sole and absolute discretion that the
amendment is necessary or appropriate in order to either (i) maintain the
status of the Agreement as set forth in the Income Tax Status paragraph or
ERISA Status paragraph above or (ii) if the Agreement would otherwise
result in significant financial penalties or be otherwise significantly
detrimental to the Bank (other than the financial impact of paying the benefits
under the Agreement), regardless of the effect of any such amendment on the
Executive or the benefits with respect to the Executive.

 

9.04.                        Termination.

 

If not terminated at an earlier date, this Agreement
shall terminate as of the earliest date on which the Bank’s obligations to the
Executive and his Beneficiary(ies) have been satisfied.  Upon termination of the Agreement, no
distributions of benefits shall be made that are not otherwise permitted by the
Agreement, unless such distributions are permitted under Code section 409A

to Code section 409A.

9.09.                        Entire Agreement.

 

This Agreement constitutes the entire agreement
between the Bank and the Executive as it relates to the benefits
under this Agreement.  This Agreement
supersedes all prior and contemporaneous agreements, understandings and
representations between the parties, whether written or oral, with respect to
the subject matter hereof.

 

9.10.                        Severability.

or invalidated in any way.

 

9.11.                        Attorneys Fees.

 

In the event that either party to this Agreement
brings an action or suit against the other party by reason of any breach of
this Agreement, the prevailing party in whose favor final judgment is entered
shall be entitled to have and recover from the losing party all reasonable
costs and expenses incurred or sustained by such prevailing party in connection
with such suit or action, including, without limitation, legal fees and court
costs.

 

9.12.                        ERISA Status.

 

This Agreement is intended to qualify as an unfunded
plan of deferred compensation that is maintained by an employer primarily for
the purpose of providing deferred compensation for a “select group of
management or highly compensated employees” as those terms are defined under
the provisions of the Employee Retirement Income Security Act of 1974, as
amended (ERISA).  Only those employees
who are responsible for the management, growth and protection of the business
of the Bank are eligible to participate in the Plan.  The Executive is fully advised of the Bank’s
financial status and has had substantial input in the negotiation and design of
this benefit arrangement.  It is
understood that the amounts payable to the Executive under this Agreement are
strictly from the general assets of the Bank and that the Executive has no
greater rights to the general assets of the Bank than any other unsecured
general creditor.  For purposes of ERISA,
the Bank shall be the named fiduciary and administrator under this Agreement.

 

IN WITNESS WHEREOF, the Executive and a duly authorized officer of the
Bank have signed this Agreement on this 22nd day of July 2005.
