and addresses are set forth on the Counterpart Signature Page attached hereto
(which persons and entities are hereinafter collectively referred to as
"Purchasers" and each individually as a "PURCHASER"). The Company and the

IN CONSIDERATION of the mutual covenants contained in this Agreement, and for
other good and valuable consideration, the receipt and sufficiency of which are

Subject to the terms and conditions of this Agreement, the Company has
authorized the sale of minimum of Fifteen (15) Units (as hereinafter defined)
and a maximum of Twenty (20) Units. A "UNIT" is defined as a security comprising
135,135 shares of the Company's newly authorized 3% Series A Preferred Stock
(the "PREFERRED STOCK") and warrants (the "WARRANTS") to purchase 40,541 shares
of the Company's common stock, $0.15 par value per share ("COMMON STOCK").
References herein to the Units include references to the shares of Preferred
Stock and the Warrants included within each Unit. In connection with the

of (a) up to 2,702,702 shares of Preferred Stock, which will be designated from
the Company's previously authorized preferred shares, (b) up to 2,702,702 shares
of Common Stock issuable upon conversion of all of the shares of the Preferred
Stock, and (c) up to 810,811 shares of Common Stock issuable upon exercise of

conducted and is duly qualified to transact business and is in good standing in
each jurisdiction in which the conduct of its business or its ownership or

accordance with its terms, except as enforceability may be limited by applicable

the Company's financial statements which are included or incorporated by
reference in the Registration Statement required to be filed pursuant to this
Agreement.

4.6 NO MATERIAL CHANGE. There has been no material adverse change and no

under the liquidation provisions of the Certificate of Designation had they held
the Shares and the Warrants on the date the Change of Control occurred and had
exercised the Warrants on such date less the Aggregate Funding Amount and the
aggregate exercise price of the Warrants.

4.19 DILUTIVE EVENT. The issuance of the Units, the underlying Shares,
Conversion Shares, Warrants, Warrant Shares, the Placement Agents warrants and
the Agent Warrant Shares, neither individually nor in the aggregate, constitute
an anti-dilution event for any existing securityholders of the Company, pursuant

assets, the Company shall ensure that the surviving or successor entity in such
transaction assumes the Company's obligations hereunder and under the

available for issuance in order to effect the conversion of all the Shares and
the exercise in full of all Warrants outstanding as of the date of such
transaction.

aggregate amount of Securities on a Common Stock equivalent basis issued to the
respective Purchaser as of the Closing date) of each Purchaser's respective
Securities shall be released from the foregoing restriction twelve (12) months
from the Closing date; and (iv) twenty-five percent (25%) (calculated based on
the aggregate amount of Securities on a Common Stock equivalent basis issued to
the respective Purchaser as of the Closing date) of each Purchaser's respective
Securities shall be released from the foregoing restriction fifteen (15) months
from the Closing date. For purposes herein, a "SALE OR HEDGING TRANSACTION" with
respect to a security shall mean (A) any pledge (except a pledge relating to a
bona fide cash loan and not for collateralizing a Sale or Hedging Transaction),
sale, contract to sell, sale of any option or contract to purchase, purchase of
any option or contract to sell, grant of any option, right or warrant to
purchase, loan or other transfer or disposition of, directly or indirectly, any
such security, or any other actions designed to achieve similar effects, (B) any
swap or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of such security, or any other actions
designed to achieve similar effects, or (C) any transaction that would be deemed
the establishment of or increase in a put equivalent position (as defined in
Rule 16a-1(h) under the Exchange Act), whether any such transaction described in

                                       9

<PAGE>

clause (A), (B) or (C) above is settled by delivery of such security, in cash or
otherwise, or any other actions designed to achieve similar effects. Any Sale or
Hedging Transaction shall be deemed to have been made with respect to the
greater of (I) the notional amount of the security subject to such transaction
and (II) the maximum amount of the security (or the cash value thereof)
deliverable in respect of such transaction.

(d) Subject to the Lock-Up Agreement provided for in Section 5.5(a) above, (i)
prior to the effective date of the Registration Statement referenced in Section
7.1(a) below (the "EFFECTIVE DATE"), Purchaser shall not transfer any Securities
except in compliance with the Securities Act and the rules and regulations
promulgated thereunder, and any transferee of Securities prior to the Effective
Date shall agree in advance in a writing acceptable to the Company to be subject
to all of the provisions of this Agreement with respect to the Securities; and
(ii) commencing as of the Effective Date, Purchaser shall not make any sale of
the Securities under the Registration Statement without effectively causing the
prospectus delivery requirement under the Securities Act to be satisfied, and
Purchaser acknowledges and agrees that on and after the Effective Date, such
Securities are not transferable on the books of the Company unless the
certificate submitted to the transfer agent evidencing Securities is accompanied
by a separate Purchaser's certificate: executed by Purchaser or by an officer
of, or other authorized person designated by, Purchaser to the effect that (I)
if the Securities have been sold in accordance with the Registration Statement,
the requirement of delivering a current prospectus has been satisfied and (II) a
representation that Section 5.5(d)(ii) of this Agreement has been complied with.

(e) The restrictions contained in Section 5.5(a), (b) and (c) are limited to the
extent necessary to prevent such restrictions from causing the Purchasers to be
considered a "GROUP" for purposes of Section 13d of the Exchange Act.

(f) Notwithstanding anything to the contrary in Sections 5.5(a), (b) and (c)
above, each Purchaser's respective obligation to hold any of the Company's
securities shall be released if there has occurred, at or prior to Closing, a
material breach in the Company's obligations or representations hereunder which
renders the Company incapable of satisfying the conditions to Closing contained
in Section 3.2(b) prior to the latest possible Closing date under Section 3.2
hereof and such breach, if curable, is not cured within fifteen (15) days after
receipt by the Company of written notice from a majority in interest (based on
the purchase commitments set forth in the Counterpart Signature Pages then held
by the Escrow Agent) of the Purchasers specifying in reasonable detail the
nature of such breach.

5.6 LEGEND. Purchaser understands and agrees that all certificates evidencing
the Shares, Warrants, Conversion Shares and Warrant Shares to be issued to such
Purchaser will bear the following legend:

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED (THE "ACT"). THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS TO THE
SECURITIES UNDER THE ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY
THAT SUCH REGISTRATION IS NOT REQUIRED.

5.7 LIMITATIONS ON USE OF PURCHASER REPRESENTATIONS. The Purchasers' several
representations and warranties made in Sections 5.1, 5.3 and 5.6 are made solely
for the purpose of permitting the Company to make a determination that the offer
and sale of the Units pursuant to this Agreement comply with applicable U.S.
federal and state securities laws and not for any other purpose. Accordingly,
the Company should not rely on such representations and warranties for any other
purpose.

                                       10

<PAGE>

5.8 PURCHASERS NOT ACTING AS A GROUP. Purchaser acknowledges and agrees that it
is acting independently with respect to this Agreement and the transactions
contemplated hereunder and not as a "group" with respect thereto for purposes of
Section 13d of the Exchange Act and, accordingly, nothing herein is intended to
give any Purchaser any rights with respect to any other Purchaser or cause it to
be a third party beneficiary of any covenants or agreements made by any other
Purchaser.

6. SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS. Notwithstanding any
investigation made by any party to this Agreement, all covenants, agreements,
representations and warranties made by the Company and the Purchasers herein and
in the certificates delivered pursuant hereto shall survive the execution of
this Agreement, the delivery to the Purchasers of the Units and the underlying
Shares and Warrants being purchased and the payment therefor.

7.  REGISTRATION OF THE COMMON STOCK; COMPLIANCE WITH THE SECURITIES ACT.

7.1      REGISTRATION PROCEDURES AND EXPENSES. The Company shall:

(a) Prior to the later to occur of December 31, 2004 and the date six months
after the initial Closing hereof, (the "FILING DEADLINE DATE"), prepare and file
with the SEC a registration statement on Form S-3 (the "REGISTRATION STATEMENT")
in order to register with the SEC the resale of all the Conversion Shares,
Warrant Shares and Agent Warrant Shares (collectively, the "REGISTRABLE
SECURITIES") by the Purchasers from time to time through underwriters, agents or
otherwise, in negotiated or market transactions or through the automated
quotation system of Nasdaq or the facilities of any national securities exchange
on which the Company's Common Stock is then traded or in privately negotiated
transactions or pursuant to such other method or methods of distribution as any
of the Purchasers may require. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 7.1 with
respect to any particular Purchaser that such Purchaser shall furnish to the
Company such information regarding itself, the Registrable Securities to be sold
by such Purchaser, and the intended method of disposition of such securities as
shall be required to effect the registration of the Registrable Securities and
to determine that the Company's filing of such Registration Statement does not
cause the Company to be in violation of any of its existing obligations to
current shareholders;

(b) use reasonable efforts, subject to the receipt of necessary information from
such Purchasers, to cause the Registration Statement to become effective as soon
as commercially practicable following the filing thereof with the SEC, but in
any event by the date (the "EFFECTIVENESS DEADLINE DATE") that is one hundred
eighty (180) days after the Filing Deadline Date;

(c) prepare and file with the SEC such amendments and supplements to the
Registration Statement and the prospectus used in connection therewith and take
such other actions as may be necessary to keep the Registration Statement
continually effective and available for use for a period of five (5) years from
the effective date of the Registration Statement (the "REGISTRATION PERIOD") or,

                                       11

<PAGE>

if earlier, until all of the Registrable Securities have been sold pursuant
thereto; and use reasonable efforts to obtain the withdrawal of any order
suspending the effectiveness of the Registration Statement or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Registrable Securities for sale in any jurisdiction in which they have been
qualified for sale, in either case at the earliest possible moment, and provide
prompt notice to the Purchaser of the withdrawal of any such order;

(d) furnish to each Purchaser and to the Placement Agent with respect to the
Registrable Securities registered under the Registration Statement such number
of copies of prospectuses and preliminary prospectuses in conformity with the
requirements of the Securities Act, in order to facilitate the public sale or
other disposition of all or any of the Registrable Securities by such
Purchasers; PROVIDED, HOWEVER, that the obligation of the Company to deliver
copies of prospectuses or preliminary prospectuses to the respective Purchasers
shall be subject to the receipt by the Company of reasonable assurances from the
respective Purchasers that the respective Purchasers will comply with the
applicable provisions of the Securities Act and of such other securities or blue
sky laws as may be applicable in connection with any use of such prospectuses or
preliminary prospectuses;

(e) file documents required of the Company for normal blue sky clearance in
states specified in writing by each of the respective Purchasers; PROVIDED,
HOWEVER, that the Company shall not be required to qualify to do business or
consent to service of process in any jurisdiction in which it is not now so
qualified or has not so consented; and

(f) bear all expenses incurred by the Company in connection with the procedures
in paragraphs (a) through (e) of this Section 7.1 and the registration of the
Registrable Securities pursuant to the Registration Statement (including
reasonable legal fees and expenses of one counsel to the Purchasers), exclusive
of underwriting discounts and commissions, which shall be the responsibility of
the Purchasers.

7.2  LIQUIDATED DAMAGES AND OTHER MATTERS.

(a) If (i) the Registration Statement is not filed by the Company with the SEC
on or prior to the twentieth (20th) day following the Closing (the "FILING
DEADLINE DATE"), then the automatic conversion feature pursuant to which the
Preferred Stock converts to Common Stock on the second (2nd) anniversary of the
Closing shall be adjusted, without any action on the part of the Company or the
Purchasers, such that the automatic conversion will be delayed by one (1) year,
such that the Preferred Stock will convert to Common Stock on the third (3rd)
anniversary of the Closing. The parties hereto agree that the liquidated damages
provided for in this Section 7.2(a) constitute a reasonable estimate of the
damages that may be incurred by the Purchasers by reason of the failure of the
Registration Statement to be filed or declared effective in accordance with the
provisions hereof.

(b) The Company shall, upon (i) the issuance by the SEC of a stop order
suspending the effectiveness of the Registration Statement or the initiation of
proceedings with respect to the Registration Statement under Section 8(d) or
8(e) of the Securities Act, (ii) the occurrence of any event or the existence of
any fact as a result of which the Registration Statement shall contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein not misleading,
or the related prospectus shall contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to

                                       12

<PAGE>

make the statements therein, in the light of the circumstances under which they
were made, not misleading, or (iii) the occurrence or existence of any pending
corporate development that, in the reasonable discretion of the Company makes it
appropriate to suspend the availability of the Registration Statement and the
related prospectus, (A) in the case of clause (ii) above, subject to the next
sentence, as promptly as practicable prepare and file, if necessary, pursuant to
applicable law, a post-effective amendment to such Registration Statement or a
supplement to the related prospectus or any document incorporated therein by
reference or file any other required document that would be incorporated by
reference to such Registration Statement and prospectus so that such
Registration Statement does not contain any untrue statement of a material fact
or omit to state any material fact required to be stated therein or necessary to
make the statements therein not misleading, and such prospectus does not contain
any untrue statement of a material fact or omit to state any material fact
required to be stated therein or necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading, as
thereafter delivered to the purchasers of the Shares being sold thereunder, and,
in the case of a post-effective amendment to the Registration Statement, subject
to the next sentence, use its reasonable efforts to cause it to be declared
effective as promptly as is practicable, and (B) give notice to the Purchasers
that the availability of the Registration Statement is suspended (a "DEFERRAL
NOTICE") and, upon receipt of any Deferral Notice, each Purchaser agrees not to
sell any Conversion Shares or Warrant Shares pursuant to the Registration
Statement until such Purchaser's receipt of copies of the supplemented or
amended prospectus provided for in clause (A) above, or until it is advised in
writing by the Company that the prospectus may be used, and has received copies
of any additional or supplemental filings that are incorporated or deemed
incorporated by reference in such prospectus. The Company will use all
reasonable efforts to ensure that the use of the prospectus may be resumed (I)
in case of clause (i) and (ii) above, as promptly as is practicable, and (II) in
the case of clause (iii) above, as soon as, in the sole judgment of the Company,
public disclosure of such material event would not be prejudicial to or contrary
to the interests of the Company or, if necessary to avoid unreasonable burden or
expense, as soon as practicable thereafter. The Company shall be entitled to
exercise its rights under this Section 7.2(b) to suspend availability of the
Registration Statement or any prospectus no more than two (2) times in any
twelve (12) month period, and any such period during which the availability of
the Registration Statement and any prospectus is suspended (a "DEFERRAL PERIOD")
shall not exceed thirty (30) days. The Company shall use all commercially
reasonable efforts to limit the duration and the number of any Deferral Periods.
Each Purchaser hereby agrees that upon receipt of any Deferral Notice from the
Company, such Purchaser shall, and shall cause each of its officers, directors,
employees, affiliates, advisors, agents and representatives to, keep
confidential all nonpublic information set forth in such notice including the
existence and terms of such Deferral Notice.

7.3 TRANSFER OF SHARES AFTER REGISTRATION. Each Purchaser agrees that it will
promptly notify the Company of any changes in the material information set forth
in the Registration Statement regarding such Purchaser or its plan of
distribution with respect to the Registrable Securities, as applicable.

7.4  INDEMNIFICATION.

(a) as used herein, the term "SELLING SHAREHOLDER" shall mean a Purchaser and,
if a Purchaser is an institution, such Purchaser's directors or trustees,
officers and employees and each person who controls Purchaser within the meaning
of the Securities Act, and it shall also refer to the Placement Agent, to the
extent reference thereto applies to the Placement Agent's sale of Agent Warrant
Shares;

                                       13

<PAGE>

(b) as used herein, the term "REGISTRATION STATEMENT" shall include any final
prospectus, exhibit, supplement or amendment included in or relating to the
Registration Statement referred to in Section 7.1; and

(c) as used herein, the term "UNTRUE STATEMENT" shall include any untrue
statement or alleged untrue statement, or any omission or alleged omission to
state in the Registration Statement a material fact required to be stated
therein or necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading.

(d) The Company agrees to indemnify and hold harmless each Selling Shareholder,
each underwriter through which sales are made pursuant to the Registration
Statement, and each person, if any, who controls an underwriter or Selling
Shareholder within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act (collectively, the "INDEMNITEES") from and
against any losses, claims, damages or liabilities to which an Indemnitee may
become subject (under the Securities Act or otherwise) insofar as such losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
arise out of, or are based upon, any untrue statement of a material fact
contained in the Registration Statement on the Effective Date thereof, or arise
out of any failure by the Company to fulfill any undertaking included in the
Registration Statement, and the Company will reimburse such Indemnitee for any
reasonable legal or other expenses reasonably incurred in investigating,
defending or preparing to defend any such action, proceeding or claim; PROVIDED,
HOWEVER, that the Company shall not be liable in any such case to the extent
that such loss, claim, damage or liability arises out of, or is based upon, an
untrue statement made in such Registration Statement in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
such Indemnitee specifically for use in preparation of the Registration
Statement, or any statement or omission in any prospectus on and after, and to
the extent that, it is corrected in any subsequent prospectus that was delivered
to such Indemnitee prior to the pertinent sale or sales by such Selling
Shareholder.

(e) Except as otherwise prohibited under the Investment Act of 1940 and the
rules and regulations promulgated thereunder, each Purchaser, severally and not
jointly, agrees to indemnify and hold harmless the Company, each person, if any,
who controls the Company within the meaning of Section 15 of the Securities Act,
each officer of the Company who signs the Registration Statement, each director
of the Company, each underwriter through which sales are made pursuant to the
Registration Statement and each person, if any, who controls such underwriter
(collectively, the "COMPANY INDEMNITEES") and any other shareholder selling
securities under such Registration Statement or any of such other shareholder's
partners, directors or officers or any person who controls such shareholder (the
"SHAREHOLDER INDEMNITEES"), from and against any losses, claims, damages or
liabilities (joint or several), but in any event not in excess of the net
proceeds received by such Purchaser in the sale of Registrable Securities giving
rise to such claim, to which the Company Indemnitees or such Shareholder
Indemnitees may become subject (under the Securities Act, the Exchange Act or
other federal or state law), insofar as such losses, claims, damages or
liabilities (or actions or proceedings in respect thereof) arise out of, or are
based upon any untrue statement of a material fact contained in the Registration
Statement on the Effective Date if such untrue statement was made in reliance

                                       14

<PAGE>

upon and in conformity with written information furnished by or on behalf of
such Purchaser specifically for use in preparation of the Registration
Statement, and the Purchaser will reimburse the Company Indemnitees or other
Shareholder Indemnitees, for any legal or other expenses reasonably incurred in
investigating, defending or preparing to defend any such action, proceeding or
claim.

(f) Promptly after receipt by any indemnified person of a notice of a claim or
the beginning of any action in respect of which indemnity is to be sought
against an indemnifying person pursuant to this Section 7.4, such indemnified
person shall notify the indemnifying person in writing of such claim or of the
commencement of such action, and, subject to the provisions hereinafter stated,
in case any such action shall be brought against an indemnified person and such
indemnifying person shall have been notified thereof, such indemnifying person
shall be entitled to participate therein, and, to the extent it shall wish, to
assume the defense thereof, with counsel reasonably satisfactory to such
indemnified person. After notice from the indemnifying person to such
indemnified person of its election to assume the defense thereof, such
indemnifying person shall not be liable to such indemnified person for any legal
expenses subsequently incurred by such indemnified person in connection with the
defense thereof; PROVIDED, HOWEVER, that if there exists or shall exist a
conflict of interest that would make it inappropriate, in the opinion of counsel
to the indemnified person, for the same counsel to represent both the
indemnified person and such indemnifying person or any affiliate or associate
thereof, the indemnified person shall be entitled to retain its own counsel at
the expense of such indemnifying person; PROVIDED, HOWEVER, that no indemnifying
person shall be responsible for the fees and expenses of more than one separate
counsel for all indemnified parties.

(g) If the indemnification provided for in this Section 7.4 is held by a court
of competent jurisdiction to be unavailable to an indemnified party with respect
to any losses, claims, damages or liabilities referred to herein, the
indemnifying party, in lieu of indemnifying such indemnified party thereunder,
shall to the extent permitted by applicable law contribute to the amount paid or
payable by such indemnified party as a result of such loss, claim, damage or
liability in such proportion as is appropriate to reflect the relative fault of
the indemnifying party on the one hand and of the indemnified party on the other
in connection with the act or omission that resulted in such loss, claim, damage
or liability, as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by a court of law by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the indemnifying party or by
the indemnified party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

(h) The obligations of the Company, Purchaser and Placement Agent under this
Section 7.4 shall survive completion of any offering of Registrable Securities
in a Registration Statement and the termination of this Agreement. No
indemnifying party, in the defense of any such claim or litigation, shall,
except with the consent of each indemnified party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such indemnified party
of a release from all liability in respect to such claim or litigation.

(i) To the extent any indemnification by an indemnifying party is prohibited or
limited by law, the indemnifying party agrees to make the maximum contribution
with respect to any amounts for which it would otherwise be liable under this
Section 7.4 to the fullest extent permitted by law; PROVIDED, HOWEVER, that no
person guilty of fraudulent misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

                                       15

<PAGE>

7.5 TERMINATION OF CONDITIONS AND OBLIGATIONS. Except as is provided in Section
5.5(a) hereof, the conditions precedent imposed by Section 5 or this Section 7
upon the transferability of the Securities shall cease and terminate as to any
particular Securities, when such Conversion Shares and/or Warrant Shares, as
applicable, shall have been effectively registered under the Securities Act and
sold or otherwise disposed of in accordance with the intended method of
disposition set forth in the Registration Statement covering such or at such
time as an opinion of counsel satisfactory to the Company shall have been
rendered to the effect that such conditions are not necessary in order to comply
with the Securities Act.

law if such Purchaser Indemnitee becomes a party to an actual or threatened
action, suit or proceeding by reason of the fact that such Purchaser Indemnitee
is or was a director, officer or shareholder of the Company, or by reason of any
action or inaction on the part of such Purchaser Indemnitee while acting in such
capacity. Such indemnification shall extend both to third party proceedings and
to proceedings brought by or in the name of the Company. Indemnification shall
not be available if the Purchaser Indemnitee did not act in good faith and in a
manner the Purchaser Indemnitee reasonably believed to be in or not opposed to
the best interests of the Company and its shareholders.

of pocket expenses, including fees and expenses of Placement Agent's legal
counsel, subject to the Company's reasonable approval, and (f) monthly advisory
