for investment and not with a view to, or for sale in connection with, any
public distribution thereof in violation of the Securities Act, it being
understood that Noteholder has the right to sell such shares in its sole

from such registration and qualification is available.

opinion reasonably satisfactory to EEI to such effect that such registration and
qualification are not required. Such Noteholder consents that the transfer
agents for the EEI Preferred Stock, the New EEI Warrants and the EEI Common
Stock may be instructed not to transfer any EEI Preferred Stock, any New EEI
Warrants, or any Conversion Share unless it receives satisfactory evidence of
compliance with the foregoing provisions, and that there may be endorsed upon
any certificate representing the EEI Preferred Stock, the New EEI Warrants, or

REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”)
OR QUALIFICATION UNDER THE BLUE SKY LAWS OF ANY JURISDICTION. SUCH SECURITIES
MAY NOT BE SOLD, ASSIGNED, TRANSFERRED OR OTHERWISE DISPOSED OF, BENEFICIALLY OR
ON THE RECORDS OF THE CORPORATION, UNLESS THE SECURITIES REPRESENTED BY THIS
CERTIFICATE HAVE BEEN REGISTERED UNDER THE SECURITIES ACT AND QUALIFIED UNDER
APPLICABLE BLUE SKY LAWS OR AN EXEMPTION FROM SUCH REGISTRATION AND
QUALIFICATION IS AVAILABLE.”  

        EEI shall, upon the request of any holder of a certificate bearing the
foregoing legend and the surrender of such certificate, issue a new certificate
without such legend if (i) the security evidenced by such certificate has been
effectively registered under the Securities Act and qualified under any
applicable state securities law and sold by the holder thereof in accordance
with such registration and qualification or (ii) such holder shall have
delivered to EEI a legal opinion reasonably satisfactory to EEI to the effect
that the restrictions set forth herein are no longer required or necessary under
the Securities Act or any applicable state law.

such securities that would otherwise result in a Change of Control (as defined
by the rules of the NASDAQ Stock Market), until EEI’s shareholders have approved
the transactions contemplated by and described in this Agreement, which approval
EEI will use all its commercially reasonable efforts to obtain within 90 days

ARTICLE VI

COVENANTS OF EEI

        6.1   Amendment to Existing Shelf Registration Statement. EEI will use
its commercially reasonable efforts to cause the existing Shelf Registration
Statement (as such term is defined in the Registration Rights Agreement entered
into pursuant to Section 3(d) of the Purchase Agreement) to be amended, to cover
a number of shares of EEI Common Stock issuable under the New EEI Warrants equal
to the amount of the previously registered, but not issued, shares of EEI Common
Stock that would have been issuable upon the conversion of the EEI Senior Notes
(estimated to be approximately 1,160,000 shares). In connection therewith, EEI
will file a post-effective amendment to the Shelf Registration Agreement within
90 days after the Closing Date and will respond to any SEC comment letter with
respect thereto within 30 days after its receipt of same.

        6.2   Demand Registration Rights. Upon written request by Noteholders
who have tendered to EEI notice of and the full exercise price for the exercise
of not less than 66-2/3% of all of the EEI Common Stock issued or issuable upon
the exercise of the New EEI Warrants, excluding the shares registered in
accordance with Section 6.1 above (estimated to be approximately 3,140,000
shares) then held by Noteholders (the “Registrable Securities”), but in any
event no sooner than 18 months following the Closing, provided EEI is then
eligible to do so under the Securities Act and the Exchange Act, and provided
that the Registrable Securities that are subject to such written request are not
eligible for resale without volume limitation pursuant to Rule 144, 144A or 145,
EEI will prepare and file with the SEC as soon as reasonably practicable (but,
subject to the provisions below, no more than 60 days from the date of the
Stockholder request), a registration statement on Form S-3 with respect to all
Registrable Securities (hereinafter referred to as the “Registration
Statement”); provided, however, that EEI may delay such filing for a period of
up to 60 days if, after consultation with counsel, EEI determines in good faith
that the filing of a Registration Statement would be detrimental to EEI and EEI
delivers a certificate (signed by its Chief Executive Officer) to the
Noteholders stating the reasonable basis of the delay. EEI may invoke this
privilege no more than twice. Upon filing the Registration Statement, EEI will
use commercially reasonable efforts to cause such Registration Statement to
become effective as soon as reasonably possible thereafter, and, subject to the
provisions below, use its reasonable best efforts to keep such Registration
Statement effective for a period of 180 days after the expiration of the New EEI
Warrants or, if earlier, until the Noteholders have sold all of the Registrable
Securities. If at any time after a Registration Statement becomes effective, EEI
advises the Noteholders in writing that due to any stop order or the existence
of material information that has not been disclosed to the public and included
in the Registration Statement it is necessary to amend the Registration
Statement, the Noteholders shall suspend any further sale of Registrable
Securities pursuant to the Registration Statement until EEI advises the
Noteholders that such stop order has been lifted or the Registration Statement
has been amended. In such event, EEI shall use reasonable efforts to cause such
stop order to be lifted or the Registration Statement to be amended as soon as
reasonably practicable. In addition, EEI may suspend use of the Registration
Statement to the extent EEI is advised by its legal counsel that such action is
reasonably necessary to comply with federal securities law. In the event the
sales of Registrable Securities of the Noteholders are suspended as provided
above, the period during which a Registration Statement must be kept effective
shall be extended for the total number of days during which sales are suspended.
In connection with and subject to the foregoing, EEI will:

12

--------------------------------------------------------------------------------

               (a)     Prepare and file with the SEC such amendments and
supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such Registration Statement effective and
current (including such amendments and supplements as requested by a Noteholder,
to the extent such request relates to information with respect to such
Noteholder), and comply with the provisions of the Securities Act with respect
to the disposition of all securities covered by such Registration Statement
during such period in accordance with the intended methods of disposition by the
Noteholders thereof as set forth in such Registration Statement.

               (b)     Furnish to the Noteholders such number of copies of such
Registration Statement, each amendment and supplement thereto, the prospectus
included in such Registration Statement (including each preliminary prospectus),
and such other documents as the Noteholders may reasonably request in order to
facilitate the disposition of the Registrable Securities owned by the
Noteholders.

               (c)     Use its commercially reasonable efforts to register or
qualify, on or prior to the date such Registration Statement becomes effective,
the Registrable Securities under the securities or “blue sky” laws of each
applicable state of the United States and do any other related acts which may be
reasonably necessary to enable the Noteholders to consummate the disposition in
such jurisdictions of the Registrable Securities owned by the Noteholders;
provided, however, that EEI will not be required (i) to qualify to do business
in any jurisdiction where it would not otherwise be required to qualify but for
this Section 6.2(c) or (ii) to consent to general service of process in any such
jurisdiction.

               (d)     Notify the Noteholders at any time when a prospectus
relating to the Registrable Securities is required to be delivered under the
Securities Act, and of the happening of any event as a result of which, or the
fact that, the prospectus included in such registration statement contains an
untrue statement of a material fact or omits any fact necessary to make the
statements therein not misleading, and EEI will prepare a supplement or
amendment to such prospectus so that, as thereafter delivered to the purchasers
of the Registrable Securities, such prospectus will not contain any untrue
statement of a material fact or omit to state any fact necessary to make the
statements therein not misleading.

               (e)     Use its commercially reasonable efforts to cause the
Registrable Securities to be listed or quoted on each securities exchange or
interdealer quotation system on which similar securities issued by EEI are then
listed or quoted.

               (f)     Provide a transfer agent for all such Registrable
Securities not later than the effective date of such Registration Statement.

               (g)     Enter into such customary agreements (including
underwriting agreements on customary terms) and take all such other actions as
the Noteholders reasonably request in order to expedite or facilitate the
disposition of the Registrable Securities.

13

--------------------------------------------------------------------------------

               (h)     Make available to each Noteholder, any underwriter
participating in any disposition pursuant to a registration statement, and any
attorney, accountant or other agent or representative retained by any such
Noteholder or underwriter (collectively, the “Inspectors”), all financial and
other records, pertinent corporate documents and properties of EEI
(collectively, the “Records”), as shall be reasonably necessary to enable them
to exercise their due diligence responsibility, and cause EEI’s officers,
directors and employees to supply all information requested by any such
Inspector in connection with such registration statement; provided that, unless
the disclosure of such Records is necessary to avoid or correct a misstatement
or omission in such registration statement or the release of such Records is
ordered pursuant to a subpoena or other order from a court of competent
jurisdiction, EEI shall not be required to provide any information under this
paragraph, (1) if EEI believes, after consultation with counsel for EEI and
counsel for the Noteholders, that to do so would cause EEI to forfeit an
attorney-client privilege that was applicable to such information or (2) if
either (i) EEI has requested and been granted from the SEC confidential
treatment of such information contained in any filing with the SEC or documents
provided supplementally or otherwise or (ii) EEI reasonably determines in good
faith that such Records are confidential and so notifies the Inspectors in
writing unless prior to furnishing any such information with respect to (i) or
(ii) such Noteholder requesting such information agrees to enter into a
confidentiality agreement in customary form and subject to customary exceptions;
and provided, further that each such Noteholder agrees that it will, upon
learning that disclosure of such Records is sought in a court of competent
jurisdiction, give notice to EEI and allow EEI at its expense, to undertake
appropriate action and to prevent disclosure of the Records deemed confidential.

               (i)     Furnish to each Noteholder and to each underwriter, if
any, a signed counterpart, addressed to such Noteholder or underwriter, of (i)
an opinion or opinions of counsel to EEI, and (ii) a comfort letter or comfort
letters from EEI’s independent registered public accountants, each in customary
form and covering such matters of the type customarily covered by opinions or
comfort letters, as the case may be, as the Noteholders included in such
offering or the managing underwriter therefor reasonably requests.

        6.3   Registration Expenses. All expenses (“Registration Expenses”)
incident to EEI’s performance of or compliance with this Article VI with respect
to any registration of the EEI Common Stock issued or issuable upon the exercise
of the New EEI Warrants will be borne by EEI, including, without limitation, all
registration and filing fees, fees and expenses of compliance with securities or
blue sky laws, printing expenses, messenger and delivery expenses, fees and
disbursements of counsel for EEI, the expense of any audit, and the, expenses
and fees for listing or quoting the securities to be registered on each
securities exchange or interdealer quotation system on which similar securities
issued by EEI are then listed or quoted. Notwithstanding the foregoing, however,
EEI shall not be obligated to pay fees and disbursements of counsel for the
holders of New EEI Warrants or Registrable Securities, and all underwriters’
discounts and commissions in respect of the sale of EEI Common Stock or
Registrable Securities shall be paid by the Noteholders, pro rata in accordance
with the number of shares sold in the offering.

        6.4   Preconditions to Participation in Underwritten Registrations. No
holder of Registrable Securities may participate in any underwritten
registration hereunder unless such person (i) agrees to sell such persons
securities on the basis provided in any customary underwriting arrangements and
(ii) completes and executes all questionnaires, powers of attorney, indemnities,
underwriting agreements, and other documents required under the terms of such
underwriting arrangements.

14

--------------------------------------------------------------------------------

        6.5   Indemnification and Contribution.

               (a)     EEI shall indemnify and hold harmless the Noteholders and
each of the Noteholders officers, directors, employees, agents, partners, legal
counsel, and accountants, and each controlling person of each of the foregoing
(within the meaning of the Securities Act) (collectively, with respect to each
Noteholder, a “Noteholder Group”) against any losses, claims, damages, or
liabilities, joint or several (or actions in respect thereof), including any of
the foregoing incurred in the settlement of any litigation, commenced or
threatened, to which any of them may be subject under the Securities Act or any
other statute or at common law, insofar as such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon (i)
any untrue statement (or alleged untrue statement) of any material fact
contained in any registration statement under which the EEI Common Stock issued
or issuable upon the exercise of the New EEI Warrants were registered under the
Securities Act or in any preliminary prospectus or final prospectus contained
therein, or in any amendment or supplement thereto, (ii) 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 (iii) any other
violation by EEI of the Securities Act or any state securities law in connection
with any such registration, and shall reimburse each such person entitled to
indemnification under this Section 6.5(a) for any legal or other expenses
reasonably incurred by such person in connection with investigating or defending
any such loss, claim, damage, liability, or action, as and when such expenses
are incurred; provided, however, that (x) EEI shall not be liable to any such
person in any such case to the extent that any such loss, claim, damage, or
liability arises out of or is based upon any untrue statement or omission made
in such registration statement, preliminary prospectus, or amendment or
supplement thereto in reliance upon and in conformity with written information
furnished to EEI by such person, specifically for use therein and (y) the
aggregate liability of EEI under this Section 6.5(a) to each Noteholder Group
shall be limited to the net amount of proceeds received by the relevant
Noteholder from the sale of Registrable Securities pursuant to any such
registration statement.

               (b)     Each of the Noteholders shall severally indemnify EEI and
each of EEI’s officers, employees, agents, directors, legal counsel, and
accountants, and each controlling person of each of the foregoing (within the
meaning of the Securities Act) against any losses, claims, damages, or
liabilities (or actions in respect thereof), including any of the foregoing
incurred in the settlement of any litigation, commenced or threatened, joint or
several, to which any of them may be subject under the Securities Act or any
other statute or at common law, insofar as, such losses, claims, damages, or
liabilities (or actions in respect thereof) arise out of or are based upon any
untrue statement (or alleged untrue statement) of any material fact contained in
any registration statement under which the EEI Common Stock issued or issuable
upon the exercise of the New EEI Warrants were registered under the Securities
Act, any preliminary prospectus or final prospectus contained therein, or in any
amendment or, supplement thereto 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, in each case to the extent that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) was
made in such registration statement, preliminary prospectus, or amendment or
supplement thereto solely in reliance upon and in conformity with written
information furnished to EEI by such Noteholder specifically for use therein,
and to reimburse such persons for any legal or other expenses reasonably
incurred in connection with investigating or defending any such loss, claim,
damage, liability, or action, as and when such expenses are incurred; provided,
however, that the aggregate liability of any Noteholder under this Section
6.5(b) shall be limited to the net amount of proceeds received by such
Noteholder from the sale of Registrable Securities pursuant to any such
registration statement.

15

--------------------------------------------------------------------------------

               (c)     If (i) an indemnified party makes a claim for
indemnification pursuant to this Section 6.5 (subject to the limitations hereof)
but it is found in a final judicial determination, not subject to further
appeal, that such indemnification may not be enforced in such case or (ii) an
indemnified party seeks contribution under the Securities Act, the Exchange Act,
or otherwise, then EEI (including for this purpose any contribution made by or
on behalf of any director of EEI, any officer of EEI who signed the registration
statement, and any controlling person of EEI) as one entity and the holders of
Registrable Securities whose fault resulted (in whole or in part) in the
applicable losses, liabilities, claims, damages, or expenses, in the aggregate
(including for this purpose any contribution by or on behalf of a person who
would be indemnified by EEI) as a second entity, shall contribute to the losses,
liabilities, claims, damages, and expenses whatsoever to which any of them may
be subject, so that such holders of Registrable Securities and EEI are each
responsible for the proportion thereof which reflects as nearly as possible the
relative fault of EEI and such holders of Registrable Securities in the
aggregate in connection with the facts which resulted in such losses,
liabilities, claims, damages, or expenses. The relative fault, in the case of an
untrue statement, alleged untrue statement, omission, or alleged omission, shall
be determined by, among other things, whether such statement, alleged statement,
omission, or alleged omission relates to information supplied by EEI or by such
holders of Registrable Securities, and the parties relative intent, knowledge,
access to information, and opportunity to correct or prevent such statement,
alleged statement, omission, or alleged omission. No person guilty of a
fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who is not
guilty of such fraudulent misrepresentation. For purposes of this Section 6.5,
each holder of Registrable Securities and each, of such holders officers,
directors, employees, agents, partners, and legal counsel and accountants, and
each controlling person of each of the foregoing (within the meaning of the
Securities Act or the Exchange Act) shall have the same rights to contribution
as a holder of Registrable Securities, and EEI and each of its officers,
employees, agents, directors, legal counsel and accountants, and each
controlling person of each of the foregoing (within the meaning of the
Securities Act or the Exchange Act) shall have the same rights to contribution
as EEI, subject in each case to the provisions of this Section 6.5. Anything in
this Section 6.5 to the contrary notwithstanding, (x) no party shall be liable
for contribution with respect to the settlement of any claim or action effected
without its written consent and (y) the aggregate liability of any Noteholder to
make contributions under this Section 6.5(c) shall be limited to the net amount
of proceeds received by such Noteholder from the sale of Registrable Securities
pursuant to any registration statement. This Section 6.5 is intended to
supersede any right to contribution under the Securities Act, the Exchange Act,
or otherwise.

16

--------------------------------------------------------------------------------

               (d)     Each party entitled to indemnification under this Section
6.5 (the “Indemnified Party”) shall give notice to the party required to provide
indemnification (the “Indemnifying Party”) promptly after such Indemnified Party
has knowledge of the commencement of any action, proceeding, or investigation in
respect of which indemnity or reimbursement may be sought as provided above;
provided, however, that the failure of such Indemnified Party to notify the
Indemnifying Party with respect to a particular action, proceeding, or
investigation shall not relieve the Indemnifying Party from any obligation or
liability (i) which it may have pursuant to this Agreement if the Indemnifying
Party is not substantially prejudiced by the failure to notify or (ii) which it
may have otherwise than pursuant to this Agreement. The Indemnifying Party shall
promptly assume the defense of any Indemnified Party with counsel reasonably
satisfactory to such Indemnified Party, and the fees and expenses of such
counsel shall be at the sole cost and expense of the Indemnifying Party. The
Indemnified Party will cooperate with the Indemnifying Party in the defense of
any action, proceeding, or investigation for which the Indemnifying Party
assumes the defense. Notwithstanding the foregoing, any such Indemnified Party
shall have the right to employ separate counsel of its own selection in any such
action, proceeding, or investigation and to participate in the defense thereof,
but the fees and expenses of such counsel shall be at the expense of such
Indemnified Party unless (x) the Indemnifying Party has agreed to pay such fees
and expenses, (y) the Indemnifying Party shall have failed promptly to assume
the defense of such action, proceeding, or investigation and employ counsel
reasonably satisfactory to such Indemnified Party, or (z) in the reasonable
judgment of such Indemnified Party there may be one or more defenses available
to such Indemnified Party which are not available to the Indemnifying Party in
respect of such action, proceeding, or investigation, in which case the
Indemnifying Party shall not have the right to assume the defense of such
action, proceeding, or investigation on behalf of such Indemnified Party. An
Indemnifying Party who is not entitled to, or elects not to, assume the defense
of an action, proceeding, or investigation shall not be obligated to pay the
fees and expenses of more than one counsel and appropriate local counsel for all
parties indemnified by such Indemnifying Party pursuant to this Section 6.5 with
respect to the same action, proceeding, or investigation, unless in the
reasonable judgment of any such Indemnified Party a conflict of interest may
exist between such Indemnified Party and any other such Indemnified Party with
respect to such action, claim, or proceeding. The Indemnifying Party shall not
be liable for the settlement by any Indemnified Party of any action, proceeding,
or investigation effected without its consent, which consent shall not be
unreasonably withheld. The Indemnifying Party shall not enter into any
settlement in any action, suit, or proceeding to which an Indemnified Party is
party unless such settlement includes a general release of the Indemnified
Party, with no payment by the Indemnified Party of consideration.

assumed in writing its obligations under this Agreement, and this Agreement
shall be binding on each party hereto and any such successor, and (b) a
Noteholder may transfer or otherwise dispose of the Senior Notes held by it that

expressly agrees to assume the Noteholders obligations under and be bound by the
terms of this Agreement, whereupon the transferee shall be entitled to all the

        7.7   Delays or Omissions; Waiver. No delay or omission to exercise any
right, power, or remedy accruing to any of EEI, the Noteholders or Quercus upon
any breach or default by the other under this Agreement shall impair any such
right, power, or remedy nor shall it be construed to be a waiver of any such
breach or default, or any acquiescence therein or in any similar breach or
default thereafter occurring; nor shall any waiver of any single breach or
default be deemed a waiver of any other breach or default theretofore or
thereafter occurring.

        7.8   Entire Agreement. This Agreement and the Exhibits hereto contain
the entire understanding of the parties with respect to the subject matter
hereof and all prior negotiations, discussions, commitments, and understandings
