         (e) PIGGYBACK REGISTRATION. Without limiting the obligations set forth
in Section 2(a) through and including 2(c) of this Agreement, if the Corporation
at any time proposes for any reason to register Primary Shares, Registrable
Shares or other shares under the Securities Act (other than on Form S-4 or Form
S-8 promulgated under the Securities Act or any successor forms thereto, (other
than the shares and warrants referenced in Section 2(d) above), it shall give
written notice to the Investor of its intention so to register such Primary
Shares, Registrable Shares or Other Shares at least 30 days before the initial
filing of such registration statement and, upon the written request, delivered
to the Corporation within 20 days after delivery of any such notice by the
Corporation, of the Investor to include in such registration Registrable Shares
(which request shall specify the number of Registrable Shares proposed to be
included in such registration and shall state that such Investor desires to sell
such Registrable Shares in the public securities markets), the Corporation shall
cause all such Registrable Shares to be included in such registration on the
same terms and conditions as the securities otherwise being sold in such
registration; PROVIDED, HOWEVER, that if the managing underwriter advises the
Corporation that the inclusion of all Registrable Shares requested to be
included in such registration would interfere with the successful marketing
(including pricing) of the Primary Shares, Registrable Shares or Other Shares
proposed to be registered by the Corporation, then the number of Primary Shares,
Registrable Shares and Other Shares proposed to be included in such registration
shall be included in the following order:

         (f) if the Corporation proposes to register Primary Shares, or Primary
Shares and Other Shares:

                  (i)      FIRST, the Primary Shares; and

                  (ii) SECOND, the Registrable Shares and Other Shares requested
         to be included in such registration (or, if necessary, such Registrable
         Shares and Other Shares PRO RATA among the holders thereof based upon
         the number of Registrable Shares and Other Shares requested to be
         registered by each such holder); or


                                       3

<page>

         (g) if the Corporation proposes to register Other Shares pursuant to a
request for registration by the holders of such Other Shares (other than
pursuant to Section 2 hereof):

                  (i) First, the Other Shares held by the parties demanding such
         registration; and

                  (ii) Second, the Registrable Shares and Other Shares (other
         than shares registered pursuant to Section 2(c)(1) hereof) requested to
         be registered by the holders hereof (or, if necessary, PRO RATA among
         the holders thereof based on the number of Registrable Shares and Other
         Shares requested to be registered by such holders).

         Section 2.        PREPARATION AND FILING.

         If and whenever the Corporation is under an obligation pursuant to the
provisions of this Agreement to effect the registration of any Registrable
Shares, the Corporation shall as expeditiously as practicable:

         (a) prepare and file with the Commission a registration statement with
respect to such Registrable Shares and use its best efforts to cause such
registration statement to become effective and, upon the request of the holders
of a majority of the Registrable Shares being registered thereunder, keep such
registration statement effective for a period of up to one hundred twenty (120)
days or until the distribution contemplated in the registration statement has
been completed; PROVIDED, HOWEVER, that (i) such 120-day period shall be
extended for a period of time equal to the period the holders of Registrable
Shares refrain from selling any securities included in such registration at the
request of an underwriter of Common Stock (or other securities) of the Company;
and (ii) in the case of any registration of Registrable Securities on Form S-3
which are intended to be offered on a continuous or delayed basis, such 120-day
period shall be extended, if necessary, to keep the registration statement
effective until all such Registrable Shares are sold, provided that Rule 415, or
any successor rule under the Securities Act, permits an offering on a continuous
or delayed basis; AND PROVIDED further that applicable rules under the
Securities Act governing the obligation to file a post-effective amendment
permit (in lieu of filing a post-effective amendment which (I) includes any
prospectus required by Section 10(a)(3) of the Securities Act or (II) reflects
facts or events representing a material or fundamental change in the information
set forth in the registration statement) the incorporation by reference, in the
registration statement, of information required to be included in (I) and (II)
above to be contained in periodic reports filed pursuant to Section 13 or 15(d)
of the Exchange Act.

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

         (c) furnish, at least five business days before filing a registration
statement that registers such Registrable Shares, a prospectus relating thereto
or any amendments or supplements relating to such a registration statement or
prospectus, to one counsel selected by the Investor (the "Investor's Counsel"),
copies of all such documents proposed to be filed (it being understood that such
five-business-day period need not apply to successive drafts of the same
document proposed to be filed so long as such successive drafts are supplied to
the Investor's Counsel in advance of the proposed filing by a period of time
that is customary and reasonable under the circumstances);


                                       4

receipt by the Corporation of any notification with respect to any comments by
the Commission with respect to such registration statement or prospectus or any
amendment or supplement thereto or any request by the Commission for the
amending or supplementing thereof or for additional information with respect
thereto, (ii) of the receipt by the Corporation of any notification with respect
to the issuance by the Commission of any stop order suspending the effectiveness
of such registration statement or prospectus or any amendment or supplement
thereto or the initiation or threatening of any proceeding for that purpose and
(iii) of the receipt by the Corporation of any notification with respect to the
suspension of the qualification of such Registrable Shares for sale in any
jurisdiction or the initiation or threatening of any proceeding for such
purposes;

         (e) use its best efforts to register or qualify such Registrable Shares
under such other securities or blue sky laws of such jurisdictions as the
Investor reasonably request and do any and all other acts and things which may
be reasonably necessary or advisable to enable the Investor to consummate the
disposition in such jurisdictions of the Registrable Shares owned by the
Investor; provided, however, that the Corporation will not be required to
qualify generally to do business, subject itself to general taxation or consent
to general service of process in any jurisdiction where it would not otherwise
be required to do so but for this paragraph (e) or to provide any material
undertaking or make any changes in its By-laws or Certificate of Incorporation
which the Board of Directors determines to be contrary to the best interests of
the Corporation or to modify any of its contractual relationships then existing;

         (f) furnish to the Investor holding such Registrable Shares such number
of copies of a summary prospectus, if any, or other prospectus, including a
preliminary prospectus, in conformity with the requirements of the Securities
Act, and such other documents as such Investor may reasonably request in order
to facilitate the public sale or other disposition of such Registrable Shares;

         (g) without limiting subsection (e) above, use its best efforts to
cause such Registrable Shares to be registered with or approved by such other
governmental agencies or authorities as may be necessary by virtue of the
business and operations of the Corporation to enable the Investor holding such
Registrable Shares to consummate the disposition of such Registrable Shares;

         (h) notify the Investor holding such Registrable Shares on a timely
basis at any time when a prospectus relating to such Registrable Shares is
required to be delivered under the Securities Act within the appropriate period
mentioned in subparagraph (a) of this Section 3, of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading in light of the circumstances then existing
and, at the request of the Investor, prepare and furnish to such Investor a
reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the offerees
of such shares, such prospectus shall not include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading in light of the
circumstances then existing;

         (i) subject to the execution of confidentiality agreements in form and
substance satisfactory to the Corporation, make available upon reasonable notice
and during normal business hours, for inspection by the Investor holding such
Registrable Shares, any underwriter participating in any disposition pursuant to
such registration statement and any attorney, accountant or other agent retained


                                       5

<page>

by the Investor or underwriter (collectively, the "Inspectors"), all pertinent
financial and other records, pertinent corporate documents and properties of the
Corporation (collectively, the "Records"), as shall be reasonably necessary to
enable them to exercise their due diligence responsibility, and cause the
Corporation's officers, directors and employees to supply all information
(together with the Records, the "Information") reasonably requested by any such
Inspector in connection with such registration statement. Any of the Information
which the Corporation determines in good faith to be confidential and of which
determination the Inspectors are so notified, shall not be disclosed by the
Inspectors unless (i) the disclosure of such Information is necessary to avoid
or correct a misstatement or an omission in the registration statement, (ii) the
release of such Information is ordered pursuant to a subpoena or other order
from a court of competent jurisdiction or (iii) such Information has been made
generally available to the public; the Investor agrees that it will, upon
learning that disclosure of such information is sought in a court of competent
jurisdiction, give notice to the Corporation and allow the Corporation, at the
Corporation's expense, to undertake appropriate action to prevent disclosure of
the Information deemed confidential;

         (j) use its best efforts to obtain from its independent certified
public accountants "cold comfort" letters addressed to the Corporation and any
selling shareholders in customary form and at customary times and covering
matters of the type customarily covered by cold comfort benefits;

         (k) use its best efforts to obtain from its counsel an opinion or
opinions in customary form addressed to the Corporation and any selling
shareholders;

         (l) in the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter of such offering. Each holder of Registrable
Shares participating in such underwriting shall also enter into and perform its
obligations under such an agreement;

         (m) provide a transfer agent and registrar (which may be the same
entity and which may be the Corporation) for such Registrable Shares and a CUSIP
number for all such Registrable Shares, in each case not later than the
effective date of such registration;

         (n) issue to any underwriter to which the Investor holding such
Registrable Shares may sell shares in such offering certificates evidencing such
Registrable Shares;

         (o) , use its best efforts to qualify such Registrable Shares for

and regulations of the Commission and make available to its security holders, as

covering a period of 12 months beginning within three months after the effective
date of the registration statement, which earnings statements shall satisfy the
provisions of Section 11 (a) of the Securities Act; and

         (q) subject to all the other provisions of this Agreement, use its best

shall forthwith discontinue disposition of the Registrable Shares pursuant to
the registration statement covering such Registrable Shares until such holders'

                                       6

<page>

receipt of the copies of the supplemented or amended prospectus contemplated by
Section 3(h) hereof, and, if so directed by the Corporation, such holder shall
deliver to the Corporation all copies, other than permanent file copies then in
such holder's possession, of the prospectus covering such Registrable Shares at
the time of receipt of such notice.

         Section 3.        EXPENSES.
                           --------

         All expenses (other than underwriting discounts and commissions
relating to the Registrable Shares, as provided in the last sentence of this
Section 4) incurred by the Corporation in complying with Section 3, including,
without limitation, all registration and filing fees (including all expenses
incident to filing with the Financial Industry Regulatory Authory, Inc.
"FINRA"), fees and expenses of complying with securities and blue sky laws,
printing expenses, fees and expenses of the Corporation's counsel and
accountants, and a $5,000 expense payment to the Investor to pay for its review
of the Corporation's filings, shall be paid by the Corporation; PROVIDED,
HOWEVER, that all underwriting discounts and selling commissions applicable to
the Registrable Shares and Other Shares shall be borne by the holders selling
such Registrable Shares and Other Shares, in proportion to the number of
Registrable Shares and Other Shares sold by each such holder.

         Section 4.        INDEMNIFICATION.

         (a) In connection with any registration of any Registrable Shares under
the Securities Act pursuant to this Agreement, the Corporation shall indemnify
and hold harmless the holders of Registrable Shares, each underwriter, broker or
any other person acting on behalf of the holders of Registrable Shares and each
other person, if any, who controls any of the foregoing persons within the
meaning of the Securities Act against any losses, claims, damages or
liabilities, joint or several (or actions in respect thereof), to which any of
the foregoing persons may become subject under the Securities Act or otherwise,
insofar as such losses, claims, damages or liabilities (or actions in respect
thereof) arise out of or are based upon an untrue statement or allegedly untrue
statement of a material fact contained in the registration statement under which
such Registrable Shares were registered under the Securities Act, the Exchange
Act or any preliminary prospectus or final prospectus contained therein or
otherwise filed with the Commission, any amendment or supplement thereto or any
document incident to registration or qualification of any Registrable Shares, or
arise out of or are based upon the 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, with respect to any prospectus, necessary
to make the statements therein in light of the circumstances under which they
were made not misleading, or any violation by the Corporation of the Securities
Act or state securities or blue sky laws applicable to the Corporation and
relating to action or inaction required of the Corporation in connection with
such registration or qualification under such state securities or blue sky laws;
and shall reimburse the holders of Registrable Shares, such underwriter, such
broker or such other person acting on behalf of the holders of Registrable
Shares and each such controlling person for any legal or other expenses
reasonably incurred by any of them in connection with investigating or defending
any such loss, claim, damage, liability or action; PROVIDED, HOWEVER, that the
Corporation shall not be liable in any such case to the extent that any such
loss, claim, damage, liability or action (including any legal or other expenses
incurred) arises out of or is based upon an untrue statement or allegedly untrue
statement or omission or alleged omission made in said registration statement,
preliminary prospectus, final prospectus, amendment supplement or document
incident to registration or qualification of any Registrable Shares in reliance
upon and in conformity with written information furnished to the Corporation by
the holders of Registrable Shares or their counsel or underwriter for use in the

                                       7

<page>

preparation thereof; PROVIDED FURTHER, HOWEVER, that the foregoing indemnity
agreement is subject to the condition that, insofar as it relates to any untrue
statement, omission or alleged omission made in any preliminary prospectus but
eliminated or remedied in the final prospectus (filed pursuant to Rule 424 of
the Securities Act), such indemnity agreement shall not inure to the benefit of
any Investor, underwriter, broker or other person acting on behalf of holders of
the Restricted Shares from whom the person asserting any loss, claim, damage,
liability or expense purchased the Restricted Shares which are the subject
thereof, if a copy of such final prospectus had been made available to such
person and such Investor, underwriter, broker or other person acting on behalf
of holders of the Registrable Shares and such final prospectus was not delivered
to such person with or prior to the written confirmation of the sale of such
Registrable Shares to such person.

         (b) In connection with any registration of Registrable Shares under the
Securities Act pursuant to this Agreement, each holder of Registrable Shares
shall severally and not jointly indemnify and hold harmless (in the same manner
and to the same extent as set forth in the preceding paragraph (a) of this
Section 5) the Corporation, each director of the Corporation, each officer of
the Corporation who shall sign such registration statement, each underwriter,
broker or other person acting on behalf of the holders of Registrable Shares and
each person who controls any of the foregoing persons within the meaning of the
Securities Act with respect to any statement or omission from such registration
statement, any preliminary prospectus or final prospectus contained therein or
otherwise filed with the Commission, any amendment or supplement thereto or any
document incident to registration or qualification of any Registrable Shares, if
such statement or omission was made in reliance upon and in conformity with
written information furnished to the Corporation or such underwriter
specifically for use in connection with the preparation of such registration
statement, preliminary prospectus, final prospectus, amendment, supplement or
document; PROVIDED, HOWEVER, that the maximum amount of liability in respect of
such indemnification shall be limited, in the case of each Seller of Registrable
Shares, to an amount equal to the net proceeds actually received by such Seller
from the sale of Registrable Shares effected pursuant to such registration.

         (c) Promptly after receipt by an indemnified party of notice of the
commencement of any action involving a claim referred to in the preceding
paragraphs of this Section 5, such indemnified party will, if a claim in respect
thereof is made against an indemnifying party, give written notice to the latter
of the commencement of such action. The failure of any indemnified party to
notify an indemnifying party of any such action shall not (unless such failure
shall have a material adverse effect on the indemnifying party) relieve the
indemnified party on account of this Section 5. In case any such action is
brought against an indemnified party, the indemnifying party will be entitled to
participate in and to assume the defense thereof, jointly with any other
indemnifying party similarly notified to the extent that it may wish, with
counsel reasonably satisfactory to such indemnified party, and after notice from
the indemnifying party to such indemnified party of its election so to assume
the defense thereof, the indemnifying party shall not be responsible for any
legal or other expenses subsequently incurred by the indemnified party in
connection with the defense thereof; PROVIDED, however, that if any indemnified
party shall have reasonably concluded that there may be one or more legal or
equitable defenses available to such indemnified party which are in conflict
with those available to the indemnifying party, or that such claim or litigation
involves or could have an effect upon matters beyond the scope of the indemnity
agreement provided in this Section 5, the indemnifying party shall not have the
right to assume the defense of such action on behalf of such indemnified party
(but shall have the right to participate therein with counsel of its choice) and
such indemnifying party shall reimburse such indemnified party and any person
controlling such indemnified party for that portion of the fees and expenses of
any counsel retained by the indemnified party which is reasonably related to the

                                       8

<page>

matters covered by the indemnity agreement provided in this Section 5. If the
indemnifying party is not entitled to, or elects not to, assume the defense of a
claim, it will not be obligated to pay the fees and expenses of more than one
counsel with respect to such claim.

         (d) If the indemnification provided for in this Section 5 is held by a
court of competent jurisdiction to be unavailable to an indemnified party with
respect to any loss, claim, damage, liability or action referred to herein, then
the indemnifying party, in lieu of indemnifying such indemnified party
hereunder, shall contribute to the amounts paid or payable by such indemnified
party as a result of such loss, claim, damage, liability or action 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 statements or omissions which resulted in such loss, claim, damage,
liability or action as well as any other relevant equitable considerations. The
relative fault of the indemnifying party and of the indemnified party shall be
determined by reference to, among other things, whether the untrue or alleged
untrue statement of a material fact or the omission or alleged 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. In
no event shall contribution obligations of this Section 5(d) exceed the net
proceeds from the offering received by such holder after deducting underwriting
fees, discounts and commissions. No person guilty of fraudulent
misrepresentation or omission shall be entitled to contribution from any person.

         Section 5.        UNDERWRITING AGREEMENT.

         Notwithstanding the provisions of Sections 2, 3, 4 and 5, to the extent
that the Investor shall enter into an underwriting or similar agreement, which
agreement contains provisions covering one or more issues addressed in such
Sections, the provisions contained in such agreement addressing such issue or
issues shall control; PROVIDED, HOWEVER, that any such agreement to which the
Corporation is not a party shall not be binding upon the Corporation. No holder
may participate in any underwritten registration hereunder unless such holder
(a) agrees to such holder's securities on the basis provided in any underwriting
arrangements and (b) completes and executes all questionnaires, powers of
attorney, indemnities, underwriting agreements and other documents reasonably
and customarily required under the terms of such underwriting arrangements.

documents required of the Corporation under the Securities Act and the Exchange
Act; and

         (c) furnish to the Investor, so long as the Investor owns any

Corporation that it has complied with the reporting requirements of Rule 144 (at
any time after ninety (90) days after the effective date of the first

         The Corporation shall not, after the date hereof, grant any
registration rights which conflict with or impair the registration rights
granted hereby. In the event the Corporation grants to any person any
registration rights that are superior in scope or substance to the registration
rights granted to the Investor, such superior rights shall be simultaneously
granted to such holders.

transferee of Registrable Shares; provided, however, that such purchaser or
transferee shall, as a condition to the effectiveness of such assignment, be
required to execute a counterpart to this Agreement agreeing to be treated as an
Investor whereupon such purchaser or transferee shall have the benefits of, and
shall be subject to the restrictions contained in, this Agreement as if such
purchaser or transferee was originally included in the definition of an Investor
herein and had originally been a party hereto

         Section 12.       ENTIRE AGREEMENT.

         This Agreement and the other writings referred to herein or therein or
delivered pursuant hereto or thereto, contain the entire agreement among the
