Adverse Effect.

                     ----------------------------------------------------------
The Purchaser hereby makes the following representations, warranties and
covenants to the Company:

        (a)  Organization and Standing of the Purchaser.  The Purchaser is a
             ------------------------------------------
limited liability company duly organized, validly existing and in good standing
under the laws of the Commonwealth of the Bahamas.

                                     -11-
<PAGE>

        (b)  Authorization and Power.  The Purchaser has the requisite
             -----------------------
corporate power and authority to enter into and perform this Agreement and to
purchase the Shares in accordance with the terms hereof. The execution, delivery
and performance of this Agreement by Purchaser and the consummation by it of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action, and no further consent or authorization of the Purchaser, its
Board of Directors or stockholders is required. This Agreement constitutes, or
shall constitute when executed and delivered, a valid and binding obligation of
the Purchaser enforceable against the Purchaser in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium, liquidation, conservatorship,
receivership, or similar laws relating to, or affecting generally the
enforcement of, creditor's rights and remedies or by other equitable principles
of general application.

        (c)  No Conflicts.  The execution, delivery and performance of this
             ------------
Agreement and the consummation by the Purchaser of the transactions contemplated
hereby and thereby or relating hereto do not and will not (i) result in a
violation of such Purchaser's charter documents or bylaws or (ii) conflict with,
or constitute a default (or an event which with notice or lapse of time or both
would become a default) under, or give to others any rights of termination,
amendment, acceleration or cancellation of any material agreement, mortgage,
deed of trust, indenture, note, bond, license, lease agreement, instrument or
obligation to which the Purchaser is a party, (iii) create or impose a lien,
charge or encumbrance on any property of the Purchaser under any agreement or
any commitment to which the Purchaser is party or by which the Purchaser is or
by which any of its properties or assets are bound or (iv) result in a violation
of any law, rule, or regulation, or any order, judgment or decree of any court
or governmental agency applicable to the Purchaser or its properties, except for
such conflicts, defaults and violations as would not, individually or in the
aggregate, prohibit or otherwise interfere with the ability of the Purchaser to
enter into and perform its obligations under this Agreement in any material
respect. The Purchaser is not required to obtain any consent, authorization or
order of, or make any filing or registration with, any court or governmental
agency in order for it to execute, deliver or perform any of its obligations
under this Agreement or to purchase the Shares in accordance with the terms
hereof, provided that for purposes of the representation made in this sentence,
the Purchaser is assuming and relying upon the accuracy of the relevant
representations and agreements of the Company herein.

        (d)  Information.  The Purchaser and its advisors, if any, have been
             -----------
furnished with all materials relating to the business, finances and operations
of the Company and materials relating to the offer and sale of the Shares which
have been requested by the Purchaser. The Purchaser and its advisors, if any,
have been afforded the opportunity to ask questions of the Company. The
Purchaser has sought such accounting, legal and tax advice as it has considered
necessary to make an informed investment decision with respect to its
acquisition of the Shares. Purchaser understands that it (and not the Company)
shall be responsible for its own tax liabilities that may arise as a result of
this investment or the transactions contemplated by this Agreement.

        (e)  Selling Restriction.  The Purchaser has the right to sell that
             -------------------
number of Shares equal in number to the number of Shares to be purchased
pursuant to this Agreement during the Investment Period. The Purchaser
covenants, however, that prior to and during the

                                     -12-
<PAGE>

Investment Period and for a period of three (3) months after any termination of
this Agreement in accordance with Article VII hereof, neither the Purchaser nor
any of its affiliates nor any entity managed by the Purchaser will ever sell any
securities of the Company (including, without limitation, any grant of any
option to purchase or acquire any right to dispose or otherwise dispose for
value, any shares of Common Stock or any securities convertible into, or
exchangeable for, or warrants to purchase any shares of Common Stock or any
swap, short sale, hedge or other agreement that transfers, in whole or in part,
the economic risk of ownership of the Common Stock) or be in a short position
with respect to shares of Common Stock of the Company in any account directly or
indirectly managed by the Purchaser, or any affiliates of the Purchaser, or any
entity managed by the Purchaser, except that during the Investment Period the
Purchaser shall have the right to sell those Shares that the Purchaser has
purchased or has accumulated for purchase during each Trading Day of a Draw Down
Pricing Period pursuant to the terms and conditions described in this Agreement
or any other similar agreement between the Company and the Purchaser. In
addition, on a daily Trading Day basis, the Purchaser agrees to restrict the
volume of sales of Shares by the Purchaser, its affiliates and any entity
managed by the Purchaser to no more than thirty percent (30%) of the total
trading volume of the Common Stock, as reported on Bloomberg Financial LP using
the HP function, for such Trading Day.

for additional information; (ii) of its receipt of notice of the issuance by the
Commission of any stop order suspending the effectiveness of the Registration
Statement or of the suspension of qualification of the Shares for offering or
sale in any jurisdiction or the initiation of any proceeding for such purpose;
and (iii) of its becoming aware of the happening of any event, which makes any
statement of a material fact made in the Registration Statement or the
Prospectus (as then amended or supplemented) untrue or which requires the making
of any additions to or changes in the Registration Statement or the Prospectus
(as then amended or supplemented) in order to state a material fact required by
the Securities Act or the regulations thereunder to be stated therein or
necessary in order to make the statements therein not misleading, or of the
necessity to amend or supplement the Prospectus (as then amended or
supplemented) to comply with the Securities Act or any other law. If at any time
the Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make all reasonable efforts to obtain
the withdrawal of such order at the earliest possible time.

        Section 4.10  Amendments to the Registration Statement.  The Company
                      ----------------------------------------
will not (i) file any amendment to the Registration Statement that relates to
the Purchaser, this Agreement or the transactions contemplated hereby in any
manner whatsoever or make any amendment or supplement to the Prospectus that
relates to the Purchaser, this Agreement or the transactions contemplated hereby
in any manner whatsoever of which, in either case, the Purchaser shall not
previously have been advised or to which the Purchaser shall reasonably object
after being so advised or (ii) so long as, in the reasonable opinion of counsel
for the Purchaser, a Prospectus is required to be delivered in connection with
any purchase of Shares by the Purchaser, file any information, documents or
reports pursuant to the Exchange Act without delivering a copy of such
information, documents or reports to the Purchaser, promptly following such
filing.

        Section 4.11  Prospectus Delivery.  The Company shall file with the
                      -------------------

following the end of each Draw Down Pricing Period, and will deliver to the
Purchaser, without charge, in such quantities as reasonably requested by the
Purchaser, copies of each form of Prospectus and Prospectus Supplement on each
Settlement Date. The Company consents to the use of the Prospectus (and of any
amendment or supplement thereto) in accordance with the provisions of the
Securities Act and with the securities or Blue Sky laws of the jurisdictions in
which the Shares may be sold by the Purchaser, in connection with the offering
and sale of the Shares and for such period of time thereafter as the Prospectus
is required by the Securities Act to be delivered in connection with sales of
the Shares. If during such period of time any event shall occur that in the
judgment of the Company and its counsel or in the opinion of counsel for the
Purchaser is required to be set forth in the Prospectus (as then amended or
supplemented) or should be set forth therein in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading, or if it is necessary to supplement or amend the Prospectus to
comply with the Securities Act or any other law, the Company will forthwith
prepare and, subject to the provisions of Section 4.10 above, file with the
Commission

                                     -15-

        Section 4.12  Other Financing. If the Company enters into any definitive
                      ---------------
financing agreement, the primary purpose of which would be to obtain equity
financing for the Company (an "Other Financing"), during the Draw Down Pricing
                               ---------------
Period, the Company shall promptly notify the Purchaser of such Other Financing.
If the Company enters into an Other Financing, including, without limitation, an
underwritten public offering, during a Draw Down Pricing Period, the Purchaser
shall have the options set forth in Section 6.1(k) hereof.  If between Draw Down
Pricing Periods the Company enters into (x) an Other Financing which provides
for the issuance of Common Stock or securities convertible, exercisable or
exchangeable for Common Stock at a net discount (after all fees and discounts
associated with the transaction) to the then current market price of the Common
Stock) or (y) the issuance of Common Stock with warrants, which have an exercise
price such that together with the price of the Common Stock would result in the
issuance of shares of Common Stock at a per share price below the then current
market price of the Common Stock, which Common Stock the Company is obligated to
register (in either case, a "PIPE Financing"), the Purchaser shall have the
                             --------------
option, which option shall be exercised no later than five (5) Trading Days
after receipt by the Purchaser of the notice of such Other Financing, to
purchase (x) up to the maximum Draw Down Amount that would be applicable under
this Agreement based on the Threshold Price equal to the price per share to be
paid for the Common Stock in the Other Financing or (y) such other amount
mutually agreed upon by the Company and the Purchaser. As used herein, "Other
Financing" shall not include the Company (i) issuing shares of Common Stock in
connection with the Company's current or future option plans, stock purchase
plans, 401K plan and stockholder rights plans, including additional shares
authorized for issuance under any such plans from time to time in the future
(the primary purpose of which is not to raise equity) or upon exercise of any
currently outstanding warrants or options, (ii) issuing shares of Common Stock,
securities convertible into Common Stock or warrants to purchase shares of
Common Stock issued for the purposes of licensing agreements, strategic
agreements and/or collaborative agreements with third parties, (iii) issuing
shares of capital stock and/or warrants in connection with the formation and
maintenance of strategic partnerships, alliances or joint ventures or for the
acquisition of products, licenses, businesses (including divisions thereof) or
other assets, (iv) issuing securities by any subsidiary of the Company, (v)
issuing the securities which are set forth on Schedule 4.12 and (vi) issuing
warrants to purchase Common Stock in connection with equipment financing or
leasing arrangements (each a "Permitted Transaction").

        Section 4.13  Notices.  The Company shall immediately notify the
                      -------

occurred or (ii) the Company has entered into an Other Financing (as defined in
Section 4.12 hereof).

                         Draw Down Terms; Call Option

        Section 6.1  Draw Down Terms.  Subject to the satisfaction of the
                     ---------------
conditions set forth in this Agreement, the parties agree as follows:

        (a)  The Company, may, in its sole discretion, issue a Draw Down Notice
with respect to a Draw Down during each Draw Down Pricing Period of up to (i)
$10,000,000 if the Threshold Price is equal to or greater than $30.00 and less
than $33.00, and (ii) an additional $1,000,000 for every $3.00 increase in the
Threshold Price above $30.00 up to $75.00; provided, that if the Threshold Price
                                           --------
equal to or greater than $75.00, then the Draw Down Amount shall be $25,000,000;
provided, however, that for every $3.00 decrease in the Threshold Price below
--------  -------
$30.00 to $15.00, the Draw Down Amount shall be decreased by $1,000,000,
incrementally; provided, further, that the Company may, in its sole discretion,
               --------  -------
issue a Draw Down Notice with respect to any Draw Down Amount at any Threshold
Price or any Draw Down Discount Percentage pursuant to terms mutually agreed
upon by the Purchaser and the Company, which Draw Down the Purchaser will be
obligated to accept. Prior to issuing any Draw Down Notice, the Company shall
have Shares registered under the Registration Statement which are valued in a
dollar amount equal to or in excess of the Draw Down Amount.

        (b)  The number of Shares to be issued in connection with each Draw
Down shall be equal to the sum of the quotients (for each Trading Day of the
Draw Down Pricing Period for which the VWAP equals or exceeds the Threshold
Price) of (x) 1/18th (or such other fraction the denominator of which equals the
number of Trading Days during the Draw Down Pricing Period) of the Draw Down
Amount divided by (y) the applicable Draw Down Discount Percentage (or such
other percentage mutually agreed upon by the parties) multiplied by the VWAP of
the Common Stock for such Trading Day.

        (c)  Only one Draw Down shall be allowed in each Draw Down Pricing
Period.

                                     -20-
<PAGE>

        (d)  The number of Shares purchased by the Purchaser with respect to
each Draw Down shall be determined on a daily basis during each Draw Down
Pricing Period and settled on the second Trading Day following the end of each
Draw Down Pricing Period (the "Settlement Date").
                               ---------------

        (e)  There shall be a minimum of five (5) Trading Days between Draw
Downs, unless otherwise mutually agreed upon between the Purchaser and the
Company.

        (f)  There shall be a maximum of twenty-four (24) monthly Draw Downs
during the term of this Agreement.

        (g)  Each Draw Down will expire on the end of the last Trading Day of
each Draw Down Pricing Period.

        (h)  If the VWAP on a given Trading Day in a Draw Down Pricing Period
is less than the Threshold Price, then the total amount of the Draw Down for the
relevant Draw Down Pricing Period will be reduced by 1/18th (or such other
fraction the denominator of which equals the number of Trading Days during the
Draw Down Pricing Period). At no time shall the Threshold Price be set below
$15.00, unless mutually agreed upon by the Company and the Purchaser. If trading
in the Common Stock is suspended for any reason for more than three (3) hours in
any Trading Day, at the Purchaser's option, the price of the Common Stock shall
be deemed to be below the Threshold Price for that Trading Day and the Draw Down
for the relevant Draw Down Pricing Period shall be reduced by 1/18th (or such
other fraction the denominator of which equals the number of Trading Days during
the Draw Down Pricing Period). Notwithstanding anything in the foregoing to the
contrary, for each Trading Day during the Draw Down Pricing Period that the VWAP
is less than the Threshold Price or is deemed to be below the Threshold Price
pursuant to the immediately preceding sentence, the Purchaser may elect in its
sole discretion to purchase Shares at a price equal to the Threshold Price
multiplied by the Draw Down Discount Percentage at the end of such Draw Down
Pricing Period. The Purchaser will inform the Company via facsimile transmission
no later than 8:00 p.m. (eastern time) on the last Trading Day of such Draw Down
Pricing Period as to the number of Shares, if any, the Purchaser chooses to
purchase under such circumstances set forth in this Section 6.1(h).

        (i)  The Company must inform the Purchaser via facsimile transmission
before 9:30 a.m. (eastern time) on the first Trading Day of the Draw Down
Pricing Period in substantially in the form attached hereto as Exhibit D (the
"Draw Down Notice") of the Draw Down Amount the Company wishes to exercise. In
-----------------
addition to the Draw Down Amount, the Company shall set the Threshold Price with
each Draw Down Notice and shall designate the first Trading Day of the Draw Down
Pricing Period. Notwithstanding anything in the foregoing to the contrary, if
the Company wishes the Draw Down Exercise Date to be the first day of the Draw
Down Pricing Period, the Draw Down Notice must be delivered to the Purchaser and
receipt of such Draw Down Notice confirmed by the Purchaser prior to 9:30 a.m.
(eastern time) on the date of such Draw Down Exercise Date.

        (j)  On each Settlement Date, the Company shall deliver the Shares
purchased by the Purchaser to the Purchaser or to The Depositary Trust Company
("DTC") on the Purchaser's behalf via the Deposit Withdrawal Agent Commission
  ---
system ("DWAC"), and upon
         ----

                                     -21-
<PAGE>

receipt of the Shares, the Purchaser shall cause payment therefor to be made to
the account designated by the Company by wire transfer of immediately available
funds provided that the Shares are received no later than 1:00 p.m., eastern
time, or next day available funds if the Shares are received thereafter.

        (k)  If during any Draw Down Pricing Period the Company shall enter
into an Other Financing (other than shares of Common Stock issued under this
Agreement or pursuant to a Permitted Transaction), the Purchaser may in its sole
discretion (i) purchase the Draw Down Amount of shares of Common Stock and/or
exercise Call Options granted during such Draw Down Pricing Period on the terms
at which the Company issued shares of Common Stock in the Other Financing during
such Draw Down Pricing Period, net of any third party's discount and fees, (ii)
purchase the Draw Down Amount of shares of Common Stock and/or exercise Call
Options granted during such Draw Down Pricing Period at the applicable Draw Down
Discount Percentage times the VWAP for such Draw Down Pricing Period, or (iii)
elect not to purchase any Shares during such Draw Down Pricing Period. The
Purchaser shall notify the Company of its election on the Trading Day preceding
the Settlement Date.

        (l)  If on the Settlement Date, the Company fails to deliver the Shares
to be purchased by the Purchaser, and such failure continues for ten (10)
Trading Days, the Company shall pay, in cash, as liquidated damages and not as a
penalty to the Purchaser an amount equal to two percent (2%) of the Draw Down
Amount for the initial thirty (30) days and each additional thirty (30) day
period thereafter until such failure has been cured, which shall be pro rated
for such periods less than thirty (30) days (the "Periodic Amount").  Cash
                                                  ----------------
payments to be made pursuant to this clause (1) shall be due and payable
immediately upon demand in immediately available cash funds.

        (m)  If during any Draw Down Pricing Period the Company reasonably
believes an event may occur which would require the suspension of the
Registration Statement, the Company shall notify the Purchaser before
commencement of trading on any Trading Day (a "Section 6.1(m) Notice") and
                                               ---------------------
reduce the number of Trading Days in such Draw Down Pricing Period. The last
Trading Day of such Draw Down Pricing Period shall be the Trading Day preceding
the receipt of the Section 6.1(m) Notice; provided, however, that if the
                                          --------  -------
Company delivers the Section 6.1(m) Notice during trading hours on a Trading
Day, then the last Trading Day of such Draw Down Pricing Period shall be the
Trading Day on which the Section 6.1(m) Notice was received by the Purchaser.

        The Purchaser will purchase the Truncated Draw Down Allocation for
each of the Trading Days prior to receipt of the Section 6.1(m) Notice, for an
aggregate purchase price determined in accordance with clauses (b) and (i) of
this Section 6.1.

        In addition, the Purchaser may, at its option, elect to purchase Shares
in an additional dollar amount equal to the product of the Draw Down Amount
Requested, first multiplied by (x) a fraction, the numerator of which equals one
(1) and the denominator of which equals eighteen (18) or such other number of
Trading Days in such Draw Down Pricing Period as the parties may have mutually
agreed upon with respect to such Draw Down Pricing Period (eighteen or such
other mutually agreed upon number being referred to herein as the "Trading Day
                                                                   -----------

minus the number of Trading Days in the reduced Draw Down Pricing Period. The
price per share for such additional dollar amount shall equal (i) the aggregate
total of Truncated Draw Down Allocation Amounts during the reduced Draw Down
Pricing Period divided by (ii) the number of Shares to be purchased during such
reduced Draw Down Pricing Period.

        Upon receipt of the Section 6.1(m) Notice, the Purchaser may (x) elect
to purchase the Common Stock at the Threshold Price for any Trading Day that the
VWAP was below the Threshold Price during the reduced Draw Down Pricing Period
in accordance with Section 6.1(i) hereof, (y) elect to purchase the Common Stock
in the additional amount as set forth in the preceding paragraph of this Section
6.1(m), and (z) elect to exercise any unexercised Call Options (for a Call
Option Amount not to exceed $1,000,000) by issuing a Call Option Notice to the
Company, in each such case, no later than 10:00 a.m. (eastern time) on the first
Trading Day after the end of the reduced Draw Down Pricing Period.  The exercise
price of the Call Option shall be based on the VWAP on the last Trading Day of
the reduced Draw Down Pricing Period (in lieu of the VWAP as specified in clause
(A) of Section 6.2(b) hereof) and otherwise determined in accordance with
Section 6.2(b) hereof.

        The Settlement Date for the Truncated Draw Down Amount exercised during
an effected Draw Down Pricing Period shall be the second Trading Day after
receipt of the Section 6.1(m) Notice.

        Section 6.2  Purchaser's Call Option.
                     -----------------------
        (a)  During each Draw Down Pricing Period, the Company at its sole
discretion may grant to the Purchaser the right to exercise multiple call
options of up to the applicable Draw Down Amount (a "Call Option"). The amount
                                                     -----------
of the Call Option shall be set forth in the Draw Down Notice. For each Trading
Day during a Draw Down Pricing Period, the Purchaser may exercise a Call Option
by providing notice to the Company of the exercise of a Call Option (the "Call
                                                                          ----
Option Notice"), substantially in the form attached hereto as Exhibit E.
--------------

        (b)  The number of shares of Common Stock to be issued in connection
with each Call Option shall equal the quotient of (i) the Call Option Amount and
(ii) the product of the applicable Draw Down Discount Percentage and the greater
of (A) the VWAP for the Common Stock on the day the Purchaser issues its Call
Option Notice and (B) the Threshold Price.

        (c)  Each Call Option exercised shall be settled on the applicable
Settlement Date.

        (d)  The Threshold Price designated by the Company in its Draw Down
Notice shall apply to each Call Option.

        (e)  For each Call Option that the Purchaser exercises pursuant to this
Section 6.2, the Purchaser must issue via facsimile a Call Option Notice to the
Company no later than 8:00 p.m. (eastern time) on the day such Call Option is
exercised. If the Purchaser does not exercise a Call Option by 8:00 p.m.
(eastern time) on the last Trading Day of the applicable

of the shares of Common Stock registered under the Registration Statement have
been issued and sold. This Agreement may be terminated at any time by mutual

to a Settlement Date.

        Section 7.3  Other Termination. The Company shall inform the Purchaser,
                     -----------------
and the Purchaser shall have the right to terminate this Agreement within the
subsequent thirty (30) days (the "Event Period"), if (x) the Company enters into
                                  ------------
an Other Financing (other than an underwritten public offering), including,
without limitation, an equity line of credit transaction and a PIPE Financing
which provides for (i) the issuance of Common Stock or securities convertible,
exercisable or exchangeable into Common Stock or the issuance of Common Stock
with warrants, which have an exercise price such that together with the price of
the Common Stock would result in the issuance of shares of Common Stock at a
discount to the then current market price of the Common Stock; provided,
                                                               --------
however, that the Purchaser's termination right shall not apply if, after the

eight month anniversary of the Closing Date, the Company enters into a PIPE
Financing at a discount of up to seven percent (7%) of the then current market

price of the Common Stock to below the then current market price of the Common
Stock, (y) a non-curable event resulting in a Material Adverse Effect except
continued losses from operations or Material Change in Ownership has occurred,
or (z) an event resulting in a Material Adverse Effect has occurred and such
event has not been cured within sixty (60) days of its occurrence.  The
Purchaser may terminate this Agreement upon one (1) day's notice during the
Event Period.  Notwithstanding anything to the contrary contained herein, the
Purchaser may not terminate this Agreement if the Company enters into an Other
Financing which provides for the issuance of Common Stock at the then current

other party and the transactions contemplated by this Agreement shall be
terminated without further action by either party. If this Agreement is
terminated as provided in Section 7.1, 7.2 or 7.3 herein, this Agreement shall
become void and of no further force and effect, except as provided in Section
9.9 hereof. Nothing in this Section 7.4 shall be deemed to release the Company

                                Indemnification

        Section 8.1  General Indemnity.
                     -----------------
        (a)  Indemnification by the Company.  The Company will indemnify and
             ------------------------------
hold harmless the Purchaser, each of its directors, fund managers and officers,
and each person, if any, who controls the Purchaser within the meaning of
Section 15 of the Securities Act or Section 20(a) of the Exchange Act from and
against any losses, claims, damages, liabilities and expenses (including
reasonable costs of defense and investigation and all reasonable attorneys'
fees) to which the Purchaser, each of its directors, fund managers and officers,
and each person, if any, who controls the Purchaser may become subject, under
the Securities Act or otherwise, insofar as such losses, claims, damages,
liabilities and expenses (or actions in respect thereof) arise out of or are
based upon, (i) any untrue statement or alleged untrue statement of a material
fact contained, or incorporated by reference, in the Registration Statement
relating to Common Stock being sold to the Purchaser (including any Prospectus
Supplement filed in connection with the transactions contemplated hereunder
which are a part of it), or any amendment or supplement to it, or (ii) the
omission or alleged omission to state in that Registration Statement or any
document incorporated by reference in the Registration Statement, a material
fact required to be stated therein or necessary to make the statements therein
not misleading, provided that the Company shall not be liable under this
                --------
Section 8.1(a) to the extent that a court of competent jurisdiction shall have
determined by a final judgment (with no appeals available) that such loss,
claim, damage, liability or action resulted directly from any such acts or
failures to act, undertaken or omitted to be taken by the Purchaser or such
person through its bad faith or willful misconduct; provided further, that the
                                                    ----------------
foregoing indemnity shall not apply to any loss, claim, damage, liability or
expense to the extent, but only to the extent, arising out of or based upon any
untrue statement or alleged untrue statement or omission or alleged omission
made in reliance upon and in conformity with written information furnished to
the Company by the Purchaser expressly for use in the Registration Statement,
any preliminary prospectus or the Prospectus (or any amendment or supplement
thereto); and provided further, that with respect to the Prospectus, the
              ----------------
foregoing indemnity shall not inure to the benefit of the Purchaser or any such
person from whom the person asserting any loss, claim, damage, liability or
expense purchased Common Stock, if copies of the Prospectus were timely
delivered to the Purchaser pursuant hereto and a copy of the Prospectus (as then
amended or supplemented if the Company shall have furnished any amendments or
supplements thereto) was not sent or given by or on behalf of the Purchaser or
any such person to such person, if required by law so to have been delivered, at
or prior to the written confirmation of the sale of the Common Stock to such
person, and if the Prospectus (as so amended or supplemented) would have cured
the defect giving rise to such loss, claim, damage, liability or expense.

     The Company will reimburse the Purchaser and each such controlling person
promptly upon demand for any legal or other costs or expenses reasonably
incurred by the Purchaser or

                                     -25-
<PAGE>

any controlling person in investigating, defending against, or preparing to
defend against any such claim, action, suit or proceeding, except that the
Company will not be liable to the extent a claim or action which results in a
loss, claim, damage, liability or expense arises out of, or is based upon, an
untrue statement, alleged untrue statement, omission or alleged omission,
included in any Registration Statement, Prospectus or Prospectus Supplement or
any amendment or supplement to the thereto in reliance upon, and in conformity
with, written information furnished by the Purchaser to the Company for
inclusion in the Registration Statement, Prospectus or Prospectus Supplement.

        (b)  Indemnification by the Purchaser.  The Purchaser will indemnify
             --------------------------------
and hold harmless the Company, each of its directors and officers, and each
person, if any, who controls the Company within the meaning of Section 15 of the
Securities Act or Section 20(a) of the Exchange Act from and against any
expenses (including reasonable costs of defense and investigation and all
attorneys' fees) to which the Company and each director, officer and person, if
any, who controls the Company may become subject, under the Securities Act or
otherwise, insofar as such losses, claims, damages, liabilities and expenses (or
actions in respect thereof) arise out of or are based upon, (i) any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or any Prospectus or Prospectus Supplement or any
amendment or supplement to it or (ii) the omission or alleged omission to state
in the Registration Statement or any Prospectus or Prospectus Supplement or any
amendment or supplement to it a material fact required to be stated therein or
necessary to make the statements therein not misleading, to the extent, but only
to the extent, the untrue statement, alleged untrue statement, omission or
alleged omission was made in reliance upon, and in conformity with, written
information furnished by the Purchaser to the Company for inclusion in the
Registration Statement, the Prospectus or Prospectus Supplement or an amendment
or supplement thereto, and the Purchaser will reimburse the Company and each
such director, officer or controlling person promptly upon demand for any legal
or other costs or expenses reasonably incurred by the Company or the other
person in investigating, defending against, or preparing to defend against any
such claim, action, suit or proceeding.

        Section 8.2  Indemnification Procedures.  Promptly after a person
                     --------------------------
receives notice of a claim or the commencement of an action for which the person
intends to seek indemnification under paragraph (a) or (b) of Section 8.1, the
person will notify the indemnifying party in writing of the claim or
commencement of the action, suit or proceeding, but failure to notify the
indemnifying party will not relieve the indemnifying party from liability under
paragraph (a) or (b) of Section 8.1, except to the extent it has been materially
prejudiced by the failure to give notice. The indemnifying party will be
entitled to participate in the defense of any claim, action, suit or proceeding
as to which indemnification is being sought, and if the indemnifying party
acknowledges in writing the obligation to indemnify the party against whom the
claim or action is brought, the indemnifying party may (but will not be required
to) assume the defense against the claim, action, suit or proceeding with
counsel satisfactory to it. After an indemnifying party notifies an indemnified
party that the indemnifying party wishes to assume the defense of a claim,
action, suit or proceeding the indemnifying party will not be liable for any
legal or other expenses incurred by the indemnified party in connection with the
defense against the claim, action, suit or proceeding except that if, in the
opinion of counsel to the indemnifying party, one or more of the indemnified
parties should be represented separately from the

                                     -26-
<PAGE>

indemnifying party in connection with a claim, action, suit or proceeding
because there may be one or more legal defenses available to it and/or other
indemnified parties that are different from or additional to those available to
the indemnifying party, the indemnifying party will pay the reasonable fees and
expenses of one separate counsel for the indemnified parties. Each indemnified
party, as a condition to receiving indemnification as provided in Paragraph (a)
or (b) or Section 8.1, will cooperate in all reasonable respects with the
indemnifying party in the defense of any action or claim as to which
indemnification is sought. No indemnifying party will be liable for any
settlement of any action effected without its prior written consent. No
indemnifying party will, without the prior written consent of the indemnified
party, effect any settlement of a pending or threatened action with respect to
which an indemnified party is, or is informed that it may be, made a party and
for which it would be entitled to indemnification, unless the settlement
includes an unconditional release of the indemnified party from all liability
and claims which are the subject matter of the pending or threatened action.

     If for any reason the indemnification provided for in this Agreement is not
available to, or is not sufficient to hold harmless, an indemnified party in
respect of any loss or liability referred to in paragraph (a) or (b) of Section
8.1, each indemnifying party will, in lieu of indemnifying the indemnified
party, contribute to the amount paid or payable by the indemnified party as a
result of the loss or liability, (i) in the proportion which is appropriate to
reflect the relative benefits received by the indemnifying party on the one hand
and by the indemnified party on the other from the sale of stock which is the
subject of the claim, action, suit or proceeding which resulted in the loss or
liability or (ii) if that allocation is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits of the
sale of stock, but also the relative fault of the indemnifying party and the
indemnified party with respect to the statements or omissions which are the
subject of the claim, action, suit or proceeding that resulted in the loss or
liability, as well as any other relevant equitable considerations.

                                 Miscellaneous

        Section 9.1  Fees and Expenses.  Each party shall bear its own fees
                     -----------------
and expenses related to the transactions contemplated by this Agreement;
provided, however, that the Company shall pay, at the Closing, all reasonable
-----------------
attorneys fees and expenses (exclusive of disbursements and out-of-pocket
expenses) incurred by the Purchaser of up to $50,000 in connection with the
preparation, negotiation, execution and delivery of this Agreement. In addition,
the Company shall pay all reasonable fees and expenses incurred by the Purchaser
in connection with any amendments, modifications or waivers of this Agreement or
incurred in connection wi th the enforcement of this Agreement, including,
without limitation, all reasonable attorneys' fees and expenses.

        (a)  The Company and the Purchaser acknowledge and agree that
irreparable damage would occur in the event that any of the provisions of this
Agreement were not performed in accordance with their specific terms or were
otherwise breached. It is accordingly agreed that the parties shall be entitled
to an injunction or injunctions to prevent or cure breaches of the provisions of
this Agreement and to enforce specifically the terms and provisions hereof or
thereof, this being in addition to any other remedy to which any of them may be
entitled by law or equity.

        (b)  Each of the Company and the Purchaser (i) hereby irrevocably
submits to the jurisdiction of the United States District Court and other courts
of the United States sitting in the State of New York for the purposes of any
suit, action or proceeding arising out of or relating to this Agreement and (ii)
hereby waives, and agrees not to assert in any such suit, action or proceeding,
any claim that it is not personally subject to the jurisdiction of such court,
that the suit, action or proceeding is brought in an inconvenient forum or that
the venue of the suit, action or proceeding is improper. Each of the Company and
the Purchaser consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address in effect for
notices to it under this Agreement and agrees that such service shall constitute
good and sufficient service of process and notice thereof. Nothing in this
Section shall affect or limit any right to serve process in any other manner
permitted by law.

        Section 9.3  Entire Agreement; Amendment.  This Agreement contains the
                     ---------------------------
entire understanding of the parties with respect to the matters covered hereby
and, except as specifically set forth herein, neither the Company nor the
Purchaser makes any representations, warranty, covenant or undertaking with

rights or obligations hereunder without the prior written consent of the Company

                                    RECITALS

         The authorized  number of shares of Parent is 1,920,000 shares of which

Common Stock,  par value $.001 per share, of which 56,458.6 shares are currently
issued and outstanding; (iii) 200,000 shares are Class C Common Stock, par value
$.001 per share,  of which 39,900 shares are currently  issued and  outstanding;
(iv) 20,000 shares are Exchangeable  Preferred Stock, par value $.001 per share,
of which 3,000  shares are  currently  issued and  outstanding;  and (v) 100,000
shares are Class B Preferred Stock,  $.001 per share, of which 15,000 shares are

1,000  shares  are Class A Common  Stock,  par value  $.01 per  share,  of which

(87%) of the  issued  and  outstanding  shares of  capital  stock of CEG will be
converted into shares of Class B Series 2 Preferred Stock of Parent, as provided

Agreement  and the  DGCL,  Merger  Sub will be  merged  with and into  CEG,  the

and  outstanding  immediately  prior to the date and time that the Merger  shall

the shares (the "Conversion  Shares") of common stock, par value $.01 per share,

Effective  Time shall be  converted  into the right to receive an  aggregate  of
15,000 shares of Class B Series 2 Preferred Stock (the "Parent Preferred Stock")
of the Parent (the "Merger  Consideration").  The Merger  Consideration shall be
allocated  pro rata among the  holders  of record of the CEG  Common  Stock (the
"Securityholders")  as of the Effective  Time in proportion to their  respective
holdings of CEG Common Stock  immediately  prior to the Effective  Time, and the
Conversion Shares shall thereupon be cancelled.  The remaining  thirteen percent
(13%) of the shares of CEG Common Stock issued and outstanding immediately prior
to the  Effective  Time shall remain issued and  outstanding  from and after the
Merger.  Shares of capital stock of CEG held by it in its treasury, if any, will
not be  deemed  outstanding  for  purposes  of this  Agreement  and  will not be
converted into shares of Parent Preferred Stock.

         2.  Effects of the Merger.  At the  Effective  Time:  (a) the  separate
existence of Merger Sub will cease, Merger Sub will be merged with and into CEG,
and  CEG  will be the  Surviving  Corporation,  pursuant  to the  terms  of this
Agreement;  (b) the Certificate of Incorporation of CEG immediately prior to the

immediately  prior to the Effective  Time will be the directors of the Surviving
Corporation;  (e) the officers of CEG  immediately  prior to the Effective  Time
will be the officers of the Surviving Corporation;  (f) each share of Merger Sub
Common  Stock  outstanding  immediately  prior  to the  Effective  Time  will be
converted  as  provided  in Section  1(a);  (g) the  Conversion  Shares  will be
converted as provided in Section 1(b);  and (h) the Merger will,  from and after
the  Effective  Time,  have  all of the  effects  provided  by  applicable  law,
including, without limitation, the DGCL.

Stock as provided in Section 1(b).

         (b) Lost,  Stolen or  Destroyed  Certificates.  In  the event  that any
             -----------------------------------------
certificate  representing  shares of CEG Common Stock to be  delivered  pursuant
hereto has been lost, stolen or destroyed,  in exchange for such lost, stolen or
destroyed  certificate,  upon the  making  of an  affidavit  of that fact by the
holder  thereof,  CEG shall  deliver  such shares of CEG Common Stock and Parent
Preferred Stock as may be required pursuant to Sections 1(b) and 3(a); provided,
however,  that CEG may, in its discretion  and as a condition  precedent to such
issuance  and  delivery,  require  the owner of such lost,  stolen or  destroyed
certificate  to  deliver  a bond  in such  sum as it may  reasonably  direct  as
indemnity  against any claim that may be made  against  CEG with  respect to the
certificate alleged to have been lost, stolen or destroyed.

         4.  Effectiveness.  This  Agreement  shall  become  effective  upon the
approval  thereof  by the  holders  of at least a  majority  of the  issued  and
outstanding  shares of  capital  stock of Merger  Sub and CEG  entitled  to vote
thereon;  provided,  however, that the Merger may be abandoned at any time prior
to the Effective Time, notwithstanding approval by such stockholders,  by mutual
decision of the boards of directors of Merger Sub and CEG.

         (a) Governing Law.  The laws of the State of Delaware,  irrespective of

and duties of the parties hereto.

         (b) Counterparts.  This  Agreement  may  be  executed  in any number of
             ------------
counterparts,  each of which  will be an  original  as regards  any party  whose
signature  appears thereon and all of which together will constitute one and the
same instrument.

         (c) Severability.    If  any  provision  of  this  Agreement,   or  the
             ------------
application  thereof,  will for any  reason  and to any  extent  be  invalid  or
unenforceable, the remainder of this Agreement and application of such provision
to other persons or circumstances will be interpreted so as reasonably to effect
the intent of the parties hereto. The parties further agree to replace such void
