regulations thereunder in connection with the distribution of the Registrable
Securities;

     (h)  prepare and promptly file with the Commission and promptly notify
counsel for the Holder of the filing of such amendment or supplement to any such

event shall have occurred as the result of which any such prospectus or any
other prospectus as then in effect would include an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances in which they were made,
not misleading;

     (i)  advise counsel for the Holder, promptly after it shall receive notice
or obtain knowledge thereof, of the issuance of any stop order by the Commission

referred to in Section 1.04(a) will be extended for any such time as there shall
exist any stop order in respect of the registration statement; and

days before the filing thereof; provided, however,

                                    Page 4 of 9

<PAGE>

that if in the opinion of counsel for the Company the filing of such amendment
or supplement is reasonably necessary to protect the Company from any
liabilities under any applicable federal or state law and such filing will not
violate applicable law, the Company many make such filings.

     Section 1.05.  INDEMNIFICATION.

     (a)  The Company will indemnify, hold harmless and defend the Holder, its
officers, directors, partners, legal counsel and accountants, each underwriter
of the Registrable Securities and each person who controls a Holder or any such
underwriter within the meaning of Section 15 of the Securities Act, against any
and all expenses, claims, losses, damages and liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereof, incident to any registration or qualification
of the Registrable Securities, or which arise out of or are based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, or any violation by the
Company  of any other rule or regulation promulgated under the Securities Act or
any state securities laws applicable to the Company and relating to action  or
inaction required of the Company in connection with any such registration,
qualification or compliance, and will reimburse each such indemnified party for
any legal and any other expenses reasonably incurred by them in connection with
investigating, preparing or defending any such claim, loss, damage, liability or
action, provided that the Company will not be liable, in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission, made in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
the Holder or and such underwriter.

     (b)  The Holder will, if Registrable Securities held by the Holder are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, and each of its officers,
directors, legal counsel and accountants, and each person who controls the
Company with the meaning of Section 15 of the Securities Act, against all
claims, losses, damages and liabilities (or action in respect thereof) arising
out of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any such registration statement, prospectus, offering
circular or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each such indemnified
person for any legal or any other damage, liability or action, in each case to
the extent, but only to the extent, that such untrue statement (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Holder.

                                    Page 5 of 9

<PAGE>

     (c)  Each person to be indemnified pursuant to this Section 1.05 (the
"Indemnified Party") will, promptly after its receipt of written notice of the
commencement of any action against such Indemnified Party in respect of which
indemnity may be sought from an indemnifying person this Section 1.05 (the
"Indemnifying Party") notify the Indemnifying Party in writing of the
commencement thereof; provided, however, that the failure of any person to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Agreement except to the extent that such Indemnifying
Party is actually prejudiced by such failure to give notice.  If any such action
shall be brought against any Indemnified Party and it shall notify an
Indemnifying Party of the commencement thereof, the Indemnifying Party will be
entitled to participate therein and, to the extent it may desire, jointly with
any other Indemnifying Party similarly notified, to assume the defense thereof,
the Indemnifying Party will not be liable to such Indemnified party under this
Section 1.05 for any legal or other expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof other than reasonable
costs of investigation unless (i) the Indemnified Party shall have employed
counsel in an action in which the Indemnified Party and Indemnifying Party are
both defendants and there is a conflict of interest between such parties that
would prevent counsel from adequately representing both parties, (ii) the
Indemnifying Party shall not have employed counsel satisfactory within the
exercise of reasonable judgment of the Indemnified Party to represent the
Indemnified party within a reasonable time after the notice of the commencement
of the action or (iii) the Indemnifying Party has authorized the employment of
counsel for the Indemnified Party at the expense of the Indemnifying Party.  The
undertaking contained in this Section 1.05 shall be in addition to any
liabilities which the Indemnifying Party may have pursuant to law.

     (d)  If the indemnification provided for in this Section 1.05 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
thereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage or expense 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, actions or omission which resulted in such loss, liability,
claim, damage or expense as well as any other relevant equitable considerations.
 The relative fault of the Indemnifying Party and of the Indemnified Party shall
be determined 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.

     Section 1.06.  LOCKUP AGREEMENT.   In consideration for the Company
agreeing to its obligations under this Article I, the Holder agrees in
connection with any firmly underwritten public offering of the Company's Common
Stock, upon request of the

                                    Page 6 of 9

underwriters, as the case may be, for such period of time from the effective

agreement described herein unless executive officers and directors of the
Company and all other holders of more than 5% of the Company's outstanding
Common Stock enter into similar agreements.

Company such information regarding the Holder and the distribution of proceeds
by the Holder as the Company may request in writing and as shall be required in
connection with an registration, qualification or compliance referred to in
Section 1.02 of this Agreement.

     Section 1.08   RULE 144 REPORTING. With a view to making available to the
Holder the benefits of certain rules and regulations of the Commission which at
any time permit the sale of the Registrable Securities to the public without
registration, the Company agrees to:

     (a)  make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

as to its compliance with the reporting requirements of said Rule 144 and of the
Securities Act and Exchange Act, a copy of the most recent annual or quarterly
report of the Company and such other reports and documents of the Company as the
Holder may reasonably request in availing Holder of any rule or regulation of
the Commission allowing the sale of any such securities without registration.

     Section 1.09.  TRANSFER OF REGISTRATION RIGHTS.   The rights of the Holder
to have the Company register the Registrable Securities granted to the Holder by
the Company under this Agreement may be assigned by the Holder to not more than
five transferees or assignees of any of the Holder's Registrable Securities,
provided that the Company is given written notice by the Holder at the time of
or within a reasonable time after said transfer, stating the name and address of
said transferee or assignee and identifying the securities with respect to which
such registration rights are being assigned, provided that no such assignment
shall increase the number of registrations that the Company may be required to
effect under this Agreement.  Any person who, in accordance with the provisions
of this Section 1.09, becomes a transferee or assignee of any of the Registrable
Securities shall, upon agreeing in writing to be bound by the terms

securities by persons other than affiliates pursuant to Commission Rule 144(k)
(or any successor provision) terminate, or (iii) until the Holder no longer owns
any of the Registrable Securities;

of the Registrable Securities;

     (d)  use its diligent good faith efforts to register or qualify the
Registrable Securities covered by such registration statement under such state
securities or Blue Sky laws of such jurisdictions as the Holder may reasonably
request, provided the Company

                                    Page 3 of 9

<PAGE>

shall be obligated to take any action to effect any such registration or
qualification pursuant to this Section 1.04(d) in any particular jurisdiction in
which the Company would be required to execute a general consent to service of
process in effecting such registration or qualification unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act;

     (e)  notify counsel for the Holder. promptly after it shall receive notice
thereof, of the time when such registration statement has become effective under
the Securities Act or a supplement to any prospectus forming a part of such
registration statement has been filed;

     (f)  notify counsel for the Holder promptly of any request by the
Commission for the amending or supplementing of such registration statement or
prospectus or for additional information;

     (g)  prepare and file with the Commission, promptly upon the request of the

Securities;

     (h)  prepare and promptly file with the Commission and promptly notify
counsel for the Holder of the filing of such amendment or supplement to any such
registration statement or prospectus as may be necessary to correct any
statements or omissions if, at the time when a prospectus relating to the
Registrable Securities is required to be delivered under the Securities Act, any
event shall have occurred as the result of which any such prospectus or any
other prospectus as then in effect would include an untrue statement of a
material fact or omit to state any material fact necessary to make the
statements therein, in the light of the circumstances in which they were made,
not misleading;

     (i)  advise counsel for the Holder, promptly after it shall receive notice
or obtain knowledge thereof, of the issuance of any stop order by the Commission
suspending the effectiveness of such registration statement under the Securities
Act or the initiation or threatening of any proceeding for such purpose, and
promptly use its best efforts to prevent the issuance of any stop order or to
obtain its withdrawal if such stop order should be issued, with it being
provided further that the effective requirements for the registration statement
referred to in Section 1.04(a) will be extended for any such time as there shall
exist any stop order in respect of the registration statement; and

supplement does not comply in all material respects with the requirements of the

days before the filing thereof; provided, however,

                                    Page 4 of 9

<PAGE>

that if in the opinion of counsel for the Company the filing of such amendment
or supplement is reasonably necessary to protect the Company from any
liabilities under any applicable federal or state law and such filing will not
violate applicable law, the Company many make such filings.

     Section 1.05.  INDEMNIFICATION.

     (a)  The Company will indemnify, hold harmless and defend the Holder, its
officers, directors, partners, legal counsel and accountants, each underwriter
of the Registrable Securities and each person who controls a Holder or any such
underwriter within the meaning of Section 15 of the Securities Act, against any
and all expenses, claims, losses, damages and liabilities (or actions in respect
thereof), including any of the foregoing incurred in settlement of any
litigation, commenced or threatened, arising out of or based on any untrue
statement (or alleged untrue statement) of a material fact contained in any
registration statement, prospectus, offering circular or other document, or any
amendment or supplement thereof, incident to any registration or qualification
of the Registrable Securities, or which arise out of or are based on any
omission (or alleged omission) to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances in which they were made, not misleading, or any violation by the
Company  of any other rule or regulation promulgated under the Securities Act or
any state securities laws applicable to the Company and relating to action  or
inaction required of the Company in connection with any such registration,
qualification or compliance, and will reimburse each such indemnified party for
any legal and any other expenses reasonably incurred by them in connection with
investigating, preparing or defending any such claim, loss, damage, liability or
action, provided that the Company will not be liable, in any such case to the
extent that any such claim, loss, damage, liability or expense arises out of or
is based on any untrue statement or omission, made in reliance upon and in
conformity with written information furnished to the Company by or on behalf of
the Holder or and such underwriter.

     (b)  The Holder will, if Registrable Securities held by the Holder are
included in the securities as to which such registration, qualification or
compliance is being effected, indemnify the Company, and each of its officers,
directors, legal counsel and accountants, and each person who controls the
Company with the meaning of Section 15 of the Securities Act, against all
claims, losses, damages and liabilities (or action in respect thereof) arising
out of or based on any untrue statement (or alleged untrue statement) of a
material fact contained in any such registration statement, prospectus, offering
circular or other document, or any omission (or alleged omission) to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading, and will reimburse each such indemnified
person for any legal or any other damage, liability or action, in each case to
the extent, but only to the extent, that such untrue statement (or alleged
omission) is made in such registration statement, prospectus, offering circular
or other document in reliance upon and in conformity with written information
furnished to the Company by or on behalf of the Holder.

     (c)  Each person to be indemnified pursuant to this Section 1.05 (the
"Indemnified Party") will, promptly after its receipt of written notice of the
commencement of any action against such Indemnified Party in respect of which
indemnity may be sought from an indemnifying person this Section 1.05 (the
"Indemnifying Party") notify the Indemnifying Party in writing of the
commencement thereof; provided, however, that the failure of any person to give
notice as provided herein shall not relieve the Indemnifying Party of its
obligations under this Agreement except to the extent that such Indemnifying
Party is actually prejudiced by such failure to give notice.  If any such action
shall be brought against any Indemnified Party and it shall notify an
Indemnifying Party of the commencement thereof, the Indemnifying Party will be
entitled to participate therein and, to the extent it may desire, jointly with
any other Indemnifying Party similarly notified, to assume the defense thereof,
the Indemnifying Party will not be liable to such Indemnified party under this
Section 1.05 for any legal or other expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof other than reasonable
costs of investigation unless (i) the Indemnified Party shall have employed
counsel in an action in which the Indemnified Party and Indemnifying Party are
both defendants and there is a conflict of interest between such parties that
would prevent counsel from adequately representing both parties, (ii) the
Indemnifying Party shall not have employed counsel satisfactory within the
exercise of reasonable judgment of the Indemnified Party to represent the
Indemnified party within a reasonable time after the notice of the commencement
of the action or (iii) the Indemnifying Party has authorized the employment of
counsel for the Indemnified Party at the expense of the Indemnifying Party.  The
undertaking contained in this Section 1.05 shall be in addition to any
liabilities which the Indemnifying Party may have pursuant to law.

     (d)  If the indemnification provided for in this Section 1.05 is held by a
court of competent jurisdiction to be unavailable to an Indemnified Party with
respect to any loss, liability, claim, damage or expense referred to therein,
then the Indemnifying Party, in lieu of indemnifying such Indemnified Party
thereunder, shall contribute to the amount paid or payable by such Indemnified
Party as a result of such loss, liability, claim, damage or expense 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, actions or omission which resulted in such loss, liability,
claim, damage or expense as well as any other relevant equitable considerations.
The relative fault of the Indemnifying Party and of the Indemnified Party shall
be determined 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.

     Section 1.06.  LOCKUP AGREEMENT.   In consideration for the Company
agreeing to its obligations under this Article I, the Holder agrees in
connection with any firmly underwritten public offering of the Company's Common
Stock, upon request of the

                                    Page 6 of 9

<PAGE>

Company or the underwriters managing such offering, not to sell, make any short
sale of, loan, grant any option for the purchase of, or otherwise dispose of an
Registrable Securities without the prior written consent of the Company or such
underwriters, as the case may be, for such period of time from the effective
date of such registration as the Company or the underwriters may specify;

Common Stock enter into similar agreements.

Company such information regarding the Holder and the distribution of proceeds

Section 1.02 of this Agreement.

     Section 1.08   RULE 144 REPORTING. With a view to making available to the
Holder the benefits of certain rules and regulations of the Commission which at
any time permit the sale of the Registrable Securities to the public without
registration, the Company agrees to:

     (a)  make and keep public information available, as those terms are
understood and defined in Rule 144 under the Securities Act;

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

     (c)  so long as any Holder owns any unregistered Registrable Securities,
furnish to the Holder forthwith upon request a written statement by the Company
as to its compliance with the reporting requirements of said Rule 144 and of the
Securities Act and Exchange Act, a copy of the most recent annual or quarterly
report of the Company and such other reports and documents of the Company as the
Holder may reasonably request in availing Holder of any rule or regulation of
the Commission allowing the sale of any such securities without registration.

     Section 1.09.  TRANSFER OF REGISTRATION RIGHTS.   The rights of the Holder
to have the Company register the Registrable Securities granted to the Holder by
the Company under this Agreement may be assigned by the Holder to not more than
five transferees or assignees of any of the Holder's Registrable Securities,
provided that the Company is given written notice by the Holder at the time of
or within a reasonable time after said transfer, stating the name and address of
said transferee or assignee and identifying the securities with respect to which
such registration rights are being assigned, provided that no such assignment
shall increase the number of registrations that the Company may be required to
effect under this Agreement.  Any person who, in accordance with the provisions
of this Section 1.09, becomes a transferee or assignee of any of the Registrable
Securities shall, upon agreeing in writing to be bound by the terms

                                    Page 7 of 9

<PAGE>

of this Agreement, be included in the terms "Holder" and "Holder" so long as
such person holds such Registrable Securities and shall be entitled to take
benefits of this Agreement.
