representing, at the time, a majority of all Registrable Securities on a 
fully diluted basis after giving effect to the conversion of all Series A 
Preferred Stock and the exercise of all Warrants (the "Requisite Holders") 
that the Company effect the registration under the Securities Act of all 
or part of the Registrable Securities (a "Requested Registration"), the 
Company will use its best efforts to effect and maintain the registration 
under the Securities Act of the Registrable Securities which the Company 
has been so requested to register by the Holders within ninety (90) days 
after receipt of such request or within sixty (60) days after receipt of 
such request if the Company is qualified to file a registration statement 
on Commission Form S-3, S-2 or any successor or similar short-form 
registration statement (collectively, "Commission Form S-3"); provided, 
however, that the Company shall not be obligated to effect a Requested 
Registration pursuant to this subdivision during the 180 day period 
immediately following the commencement of the Company's public offering of 
equity securities nor shall the Company be obligated to effect more than 
three (3) Requested Registrations under this Section 2(a)(i).  Subject to 
subdivision (f), the Company may include in such Requested Registration 
other securities of the Company for sale, for the Company's account or for 
the account of any other person, if and to the extent that the managing 
underwriter determines that the inclusion of such additional shares will 
not interfere with the orderly sale of the underwritten securities at a 
price range acceptable to the requesting Holders.  Upon receipt of a 
written request pursuant to this subdivision (a) the Company shall 
promptly give written notice of such request to all Holders, and all 
Holders shall be afforded the opportunity to participate in such request 
as follows:  The Company will be obligated to include in the Requested 
Registration such number of Registrable Securities of any Holder joining 
in such request as are specified in a written request by the Holder 
received by the Company within 20 days after receipt of such written 
notice from the Company.
(ii)	In addition to the rights of the Holders under Section 2(a)(i) 
above, as a condition to the mandatory conversion of the Series A 
Preferred Stock pursuant to the Certificate of Designation designating the 
Series A Preferred Stock, the Company shall file and cause to become 
effective at the time set forth in the Certificate of Designation a shelf 
registration statement on Commission Form S-3 or another appropriate form 
pursuant to Rule 415 under the Securities Act or any similar rule that may 
be adopted by the Commission, with respect to all the Registrable 
Securities requested by such Holders to be included in such shelf 
registration statement (each, a "Shelf Registration").  The Company will 
use its best efforts to amend such Shelf Registration from time to time at 
the request of any Holders to cover additional Registrable Securities held 
by such Holders, to keep such Shelf Registration continuously effective 
for a period of one year following the mandatory conversion of the Series 
A Preferred Stock or, if earlier, until all Registrable Securities covered 
thereby have been sold and to take all actions required to permit the sale 
of Registrable Securities thereunder.  All other provisions of this 
Agreement regarding registration procedures shall apply to a Shelf 
Registration.
(iii)	In the event the Requisite Holders request the assistance of 
the Company in order to effect a sale of Registrable Securities under such 
Shelf Registration pursuant to an underwritten offering, then (aa) the 
Company will use its best efforts to assist in the sale of Registrable 
Securities in such underwritten offering under such Shelf Registration as 
if such offering were a Requested Registration under this Agreement, (bb) 
all Holders shall have a right to participate in such underwritten 
offering on the same basis as if such underwritten offering were a 
Requested Registration under Section 2(a)(i), with the cutback provisions 
of Section 2(f) being applied with respect to such offering and (cc) the 
other provisions of this Agreement relating to Requested Registrations 
shall apply, insofar as reasonably possible, to such underwritten offering 
mutatis mutandis.

(b)	Incidental Registration.  If the Company for itself or any of 
its security holders (unless pursuant to demand registration rights 
granted with respect to Other Securities in compliance with this Agreement 
if and to the extent that the managing underwriter determines that the 
inclusion of Registrable Securities will interfere with the orderly sale 
of the underwritten securities at a price range acceptable to the holders 
of such Other Securities) shall at any time or times after the date hereof 
determine to register under the Securities Act any shares of its capital 
stock or other securities (other than: (i) the registration of an offer, 
sale or other disposition of securities solely to employees of, or other 
persons providing services to, the Company, or any subsidiary pursuant to 
an employee or similar benefit plan; or (ii) relating to a merger, 
acquisition or other transaction of the type described in Rule 145 under 
the Securities Act or a comparable or successor rule, registered on Form 
S-4 or similar or successor forms, including resales of such securities), 
on each such occasion the Company will notify each Holder of such 
determination at least thirty (30) days prior to the filing of such 
registration statement, and upon the request of any Holder given in 
writing within twenty (20) days after the receipt of such notice, the 
Company will use its best efforts as soon as practicable thereafter to 
cause any of the Registrable Securities specified by any such Holder to be 
included in such registration statement to the extent such registration is 
permissible under the Securities Act and subject to the conditions of the 
Securities Act (an "Incidental Registration").

(c)	Registration Statement Form.  The Company shall, if permitted 
by law, effect any registration requested under Section 2 by the filing of 
a registration statement on Commission Form S-3 and shall use its best 
efforts to take any action necessary to maintain its eligibility to 
utilize Commission Form S-3 to permit resales as requested by the Holders 
with respect to Transactions Involving Secondary Offerings as described in 
General Instruction I.B.3 of Commission Form S-3.

(d)	Expenses.  The Company shall pay all Registration Expenses 
incurred in connection with any Incidental Registration and any Requested 
Registrations, and those holders of Registrable Securities participating 
in such registrations shall bear a pro rata share of any applicable 
underwriting discounts and commissions.

(e)	Effective Registration Statement.  A Requested Registration or 
an Incidental Registration requested pursuant to Section 2(a) or Section 
2(b), respectively, shall not be deemed to have been effected unless it 
has become effective with the Commission.  Notwithstanding the foregoing, 
a registration statement will not be deemed to have been effected if: (i) 
after it has become effective with the Commission, such registration is 
interfered with by any stop order, injunction, or other order or 
requirement of the Commission or other governmental agency or any court 
proceeding for any reason other than a misrepresentation or omission by 
any Holder; or (ii) the conditions to closing specified in the purchase 
agreement or underwriting agreement entered into in connection with such 
registration are not satisfied, other than solely by reason of some act or 
omission by any Holder.

(f)	Priority in Incidental Registration.  If an Incidental 
Registration is an underwritten registration initiated by the Company, and 
the managing underwriters shall give written advice to the Company that, 
in their opinion, market conditions dictate that no more than a specified 
maximum number of securities (the "Underwriter's Maximum Number") could 
successfully be included in such Incidental Registration, then:  (i) 
first, the Company shall be entitled to include in such registration that 
number of securities which the Company proposes to offer and sell for its 
own account in such registration and which does not exceed the 
Underwriter's Maximum Number; and (ii) second, the Company will be 
obligated and required to include in such registration that number of 
shares of Registrable Securities which shall have been requested by the 
Holders thereof having registration rights hereunder and shares held by 
other holders of securities of the Company entitled to participate in such 
Incidental Registration.  If less than all of the Registrable Securities 
or shares held by other holders entitled to participate in such 
registration requested to be included in any such registration by the 
holders of such securities can be so included due to these priority 
requirements, then each requesting holder's request shall be granted on an 
pro rata basis with the other requesting Holders and holders of securities 
of the Company having rights to participate in such Incidental 
Registration on a pro rata basis.

(g)	Notwithstanding anything in paragraphs (a) and (b) of this 
Section 2, the Company shall have the right to (i) delay any registration 
of Registrable Securities requested pursuant to paragraph (a) or (b) of 
this Section 2 or (ii) upon written notice to the Holders, prohibit the 
Holders from selling Registrable Securities under the Shelf Registration, 
in either case for up to sixty (60) days if such registration or sale, as 
applicable, would, in the judgment of the Company's Board of Directors, 
substantially interfere with any material transaction being considered at 
the time of receipt of the request from the Holders or at the time of the 
sale prohibition notice, as applicable; provided however, that the 
provisions of this paragraph (g) shall not be invoked by the Company on 
more than two occasions during any period of 365 days and shall not be 
invoked so as to delay any registration or sale of Registrable Securities 
for more than sixty (60) days; and provided further, that the Holders 
shall not unreasonably withhold their consent to a delay beyond sixty (60) 
days if requested by the Company.  The time period during which any sale 
prohibition is in effect under this Section 2(g) shall be added to the 
time period for which a registration statement is otherwise required to 
remain effective under Section 2(a) of this Agreement.
3.	Registration Procedures.
(a)	If and whenever the Company is required to use its best 
efforts to effect the registration of any Registrable Securities under the 
Securities Act as provided in Section 2, the Company, as expeditiously as 
possible and subject to the terms and conditions of Section 2, will:

	(i)prepare and file with the Commission the requisite 
registration statement to effect such registration and use its best 
efforts to cause such registration to become and remain effective;

	(ii)permit any Holder which, in the reasonable judgment of the 
Holder, might be deemed to be an underwriter or a controlling person of 
the Company, to participate in the preparation of such registration 
statement and to require the insertion therein of material, furnished to 
the Company in writing, which in the reasonable judgment of such Holder 
and its counsel should be included and which is not reasonably objected to 
by the Company and its Counsel; 

	(iii)prepare and file with the Commission such amendments and 
supplements to such registration statement and the prospectus used in 
connection therewith as may be necessary to keep such registration 
statement effective and to comply with the provisions of the Securities 
Act with respect to the disposition of all securities covered by such 
registration statement until the earlier of such time as all of such 
securities have been disposed of in accordance with the intended methods 
of disposition by the seller or sellers thereof set forth in such 
registration statement or the expiration of 180 days after such 
registration statement becomes effective;

	(iv)furnish to the Holders such number of conformed copies of 
such registration statement and of each such amendment and supplement 
thereto (in each case including all exhibits), such number of copies of 
the prospectus contained in such registration statement (including each 
preliminary prospectus and any summary prospectus) and any other 
prospectus filed under Rule 424 under the Securities Act, in conformity 
with the requirements of the Securities Act, and such other documents, as 
the purchaser or any Holder of Registrable Securities to be sold under 
such registration statement may reasonably request in order to facilitate 
the distribution of such Registrable Securities;

	(v)use its best efforts to register or qualify all Registrable 
Securities covered by such registration statement under such other United 
States state securities or blue sky laws of such jurisdictions as any 
Holder of Registrable Securities to be sold under registration statement 
shall reasonably request, to keep such registration or qualification in 
effect for so long as such registration remains in effect, and take any 
other action which may be customary in similar offerings to enable the 
Holder of Registrable Securities to be sold under such registration 
statement to consummate the disposition in such jurisdictions of the 
securities owned by such Holder, except that the Company shall not for any 
such purpose be required to (a) qualify generally to do business as a 
foreign corporation in any jurisdiction wherein it would not but for the 
requirements of this subdivision (v) be obligated to be so qualified, or 
(b) subject itself to taxation in any such jurisdiction.

	(vi)use its best efforts to cause all Registrable Securities 
covered by such registration statement to be registered with or approved 
by such other United States state governmental agencies or authorities as 
may be necessary to enable the Holder of Registrable Securities to be sold 
under such registration statement to consummate the intended disposition 
of such Registrable Securities;

	(vii)in the event of the issuance of any stop order suspending 
the effectiveness of the registration statement, or of any order 
suspending or preventing the use of any related prospectus or suspending 
the qualification of any Registrable Securities included in such 
registration statement for sale in any jurisdiction, the Company shall use 
its best efforts promptly to obtain the withdrawal of such order; 

	(viii)use it best efforts to furnish to the Holders of 
Registrable Securities to be sold under such registration statement (1) an 
opinion, dated the effective date of the registration statement, of the 
independent counsel representing the Company for the purposes of such 
registration, addressed to the underwriters, if any, and to the Holders 
making such request, stating that such registration statement has become 
effective under the Securities Act and that (i) to the best knowledge of 
such counsel, no stop order suspending the effectiveness thereof has been 
issued and no proceedings for that purpose have been instituted or are 
pending or contemplated under the Securities Act; (ii) the registration 
statement, the related prospectus, and each amendment or supplement 
thereto, comply as to form in all material respects with the requirements 
of the Securities Act and the applicable rules and regulations of the 
Commission thereunder (except that such counsel need express no opinion as 
to financial statements contained therein);  (iii) such counsel has no 
reason to believe that either the registration statement or the 
prospectus, or any amendment or supplement thereto, contains any untrue 
statement of a material fact or omits a material fact necessary to make 
the statements therein, in light of the circumstances under which they 
were made, not misleading; (iv) the descriptions in the registration 
statement or the prospectus, or any amendment or supplement thereto, of 
all legal and governmental matters and contracts and other legal documents 
or instruments are accurate and fairly present the information required to 
be shown; and (v) such counsel does not know of any legal or governmental 
proceedings, pending or contemplated, required to be described in the 
registration statement or prospectus, or any amendment or supplement 
thereto, which are not described as required nor of any contracts or 
documents or instruments of a character required to be described in the 
registration statement or prospectus, or any amendment or supplement 
thereto or to be filed as exhibits to the registration statement which are 
not described and filed as required; and (2) a letter, dated the effective 
date of the registration statement, from the independent certified public 
accountants of the Company, addressed to the underwriters, if any, and to 
the Holders making such request, stating that they are independent 
certified public accountants within the meaning of the Securities Act and 
that in the opinion of such accountants, the financial statements and 
other financial data of the Company included in the registration statement 
or the prospectus, or any amendment or supplement thereto, comply as to 
form in all material respects with the applicable accounting requirements 
of the Securities Act.

	Such opinion of counsel shall additionally cover such legal 
matters with respect to the registration in respect of which such opinion 
is being given as the Holders may reasonably request.  Such letter from 
the independent certified public accountants shall additionally cover such 
other financial matters (including information as to the period ending not 
more than five business days prior to the date of such letter) with 
respect to the registration in respect of which such letter is being given 
as the Holders may reasonably request.

	(ix)immediately notify the Holders of Registrable Securities 
included in such registration statement at any time when a prospectus 
relating thereto is required to be delivered under the Securities Act, of 
the happening of any event as result of which the prospectus included in 
such registration statement, as then in effect, includes an untrue 
statement of material fact or omits to state any material fact required to 
be stated therein or necessary to make the statements therein not 
misleading in the light of the circumstances under which they were made, 
and at the request of the Holders promptly prepare and furnish to the 
Holders 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 purchasers of such securities, 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 the light of the circumstances under which they were 
made;

	(x)otherwise use its best efforts to comply with all 
applicable rules and regulations of the Commission, and make available to 
its security holders, as soon as reasonably practicable, an earnings 
statement covering the period of at least twelve months, but not more than 
eighteen months, beginning with the first full calendar month after the 
effective date of such registration statement, which earnings statement 
shall satisfy the provisions of Section 11(a) of the Securities Act and 
Rule 158 thereunder, and not file any amendment or supplement to such 
registration statement or prospectus to which any Holder shall have 
reasonably objected in writing on the grounds that such amendment or 
supplement does not comply in all material respects with the requirements 
of the Securities Act or of the rules or regulations thereunder, having 
been furnished with a copy thereof at least two business days prior to the 
filing thereof to the extent reasonably possible;

	(xi)provide a transfer agent for all Registrable Securities 
covered by such registration statement not later than the effective date 
of such registration statement; 

	(xii)use its best efforts to cause to be quoted or listed all 
Registrable Securities covered by such registration statement on NASDAQ 
and any securities exchange on which any of the Registrable Securities are 
then quoted or listed; and

of the Holders including, without limitation, participation by senior 
management in presentations to prospective purchasers and other marketing 
activities consistent with those customarily conducted by issuers in 
connection with primary offerings of securities.

(b)	As a condition to the Company's obligation under this Section 
with respect to any Holder, the Company may require such Holder of 
Registrable Securities to be sold under such registration statement, at 
the Company's expense, to furnish the Company with such information and 
undertakings as it may reasonably request regarding such Holder and the 
distribution of such securities as the Company may from time to time 
reasonably request in writing.

(c)	Each Holder, by execution of this Agreement, agrees (A) that 
upon receipt of any notice of the Company of the happening of any event of 
the kind described in subdivision (a)(ix) of this Section 3, such Holder 
will forthwith discontinue its disposition of Registrable Securities 
pursuant to the registration statement relating to such Registrable 
Securities until the receipt by such Holder of the copies of the 
supplemented or amended prospectus contemplated by subdivision (a)(ix) of 
this Section 3 and, if so directed by the Company, will deliver to the 
Company all copies other than permanent file copies, then in possession of 
the Holders of the prospectus relating to such Registrable Securities 
current at the time of receipt of such notice and (B) that it will 
immediately notify the Company, at any time when a prospectus relating to 
the registration of such Registrable Securities is required to be 
delivered under the Securities Act, of the happening of any event as a 
result of which information previously furnished by such Holder to the 
Company for inclusion in such prospectus contains an untrue statement of a 
material fact or omits to state any material fact required to be stated 
therein or necessary to make the statements therein not misleading in the 
light of the circumstances under which they were made.  In the event the 
Company or any such Holder shall give any such notice, the period referred 
to in subdivision (a)(iii) of this Section 3 shall be extended by a number 
of days equal to the number of days during the period from and including 
the giving of notice pursuant to subdivision (a)(ix) of this Section 3 to 
and including the date when such Holder shall have received the copies of 
the supplemented or amended prospectus contemplated by subdivision (a)(ix) 
of this Section 3.
4.	Underwritten Offerings.
(a)	Underwritten Offering.  In connection with any underwritten 
offering pursuant to a registration requested under Section 2(a), the 
Company will enter into an underwriting agreement with the underwriters 
for such offering, such agreement to be in form and substance reasonably 
satisfactory to all Holders requesting such registration and such Holders' 
underwriters in their reasonable judgment and to contain such 
representations and warranties by the Company and such other terms as are 
customarily contained in agreements of that type, including, without 
limitation, indemnities to the effect and to the extent provided in 
Section 6.  Each such Holder shall be a party to such underwriting 
agreement and may, at its option, require that any or all of the 
representations and warranties by, and the other agreements on the part 
of, the Company to and for the benefit of such underwriters shall also be 
made to and for the benefit of each such Holder and that any or all of the 
conditions precedent to the obligations of such underwriters under such 
underwriting agreement be conditions precedent to the obligations of each 
such Holder.  No Holder requesting such registration shall be required to 
make any representations or warranties to or agreements with the Company 
or the underwriters other than representations, warranties or agreements 
regarding such Holder and its intended method of distribution and any 
other representation required by law.

(b)	Selection of Underwriters.  If a Requested Registration 
pursuant to Section 2(a) involves an underwritten offering, then the 
Company shall select the underwriter from underwriting firms of national 
reputation, with expertise in comparable offerings by companies engaged in 
businesses similar to that of the Company, subject to the approval of the 
Holders of a majority of the Registrable Securities to be included in such 
registration, which approval shall not be unreasonably withheld.  

(c)	Holdback Agreements.  Each Holder agrees, if so reasonably 
required by the managing underwriter in a registration pursuant to Section 
2, not to effect any public sale or distribution of Registrable Securities 
or sales of such Registrable Securities pursuant to Rule 144 or Rule 144A 
under the Securities Act, during the seven (7) days prior to and the 180 
days after any firm commitment underwritten registration pursuant to 
Section 2 has become effective (except as part of such underwritten 
registration) or, if the managing underwriter advises the Company that, in 
its opinion, no such public sale or distribution should be effected for a 
period of not more than 180 days after such underwritten registration in 
order to complete the sale and distribution of securities included in such 
registration and the Company gives notice to such effect to such Holders 
of such advice, each Holder shall not effect any public sale or 
distribution of Registrable Securities or sales of such Registrable 
Securities pursuant to Rule 144 or Rule 144A under the Securities Act 
during such period after such underwritten registration, except as part of 
such underwritten registration, whether or not such Holder participates in 
such registration.
5.	Preparation, Reasonable Investigation.
In connection with the preparation and filing of each registration 
statement under the Securities Act other than pursuant to an underwritten 
offering, the Company will give the Holders of Registrable Securities to 
be sold under such registration statement, the underwriters, if any, and 
their respective counsel and accountants, drafts and final copies of such 
registration statement, each prospectus included therein or filed with the 
Commission and each amendment thereof or supplement thereto, at least 5 
business days prior to the filing thereof with the Commission, and will 
give each of them such access to its books and records and such 
opportunities to discuss the business of the Company with its officers and 
the independent public accountants who have certified its financial 
statements as shall be necessary, in the opinion of such Holders and such 
underwriters' respective counsel, to conduct a reasonable investigation 
within the meaning of the Securities Act.
6.	Indemnification and Contribution.
(a)	Indemnification by the Company.  In the event of any 
registration under the Securities Act pursuant to Section 2 of any 
Registrable Securities covered by such registration, the Company will, and 
hereby does, indemnify and hold harmless each Holder of Registrable 
Securities to be sold under such registration statement, each such 
Holder's legal counsel, each other person who participates as an 
underwriter in the offering or sale of such securities (if so required by 
such underwriter as a condition to including the Registrable Securities of 
the Holders in such registration) and each other person, if any, who 
controls any such Holder or any such underwriter within the meaning of the 
Securities Act (collectively, the "Indemnified Parties"), against any 
losses, claims, damages or liabilities, joint or several, to which the 
Holders or underwriter or controlling person may become subject under the 
Securities Act or otherwise, insofar as such losses, claims, damages or 
liabilities (or actions or proceedings, whether commenced or threatened, 
in respect thereof) arise out of or are based upon any untrue statement or 
alleged untrue statement of any material fact contained in any 
registration statement under which such securities were registered under 
the Securities Act, any preliminary prospectus, final prospectus or 
summary prospectus contained therein or any document incorporated therein 
by reference, or any amendment or supplement thereto, or any omission or 
alleged omission to state therein a material fact required to be stated 
therein or necessary to make the statements therein not misleading, or 
arise out of any violation by the Company of any rule or regulation 
promulgated under the Securities Act or state securities law applicable to 
the Company and relating to action or inaction required of the Company in 
connection with any such registration, and the Company will reimburse the 
Indemnified Parties for any legal or any other expenses reasonably 
incurred by them in connection with investigating or defending any such 
loss, claim, liability, action or proceeding; provided, however, that the 
Company shall not be liable to any Indemnified Party in any such case to 
the extent that any such loss, claim, damage, liability (or action or 
proceeding in respect thereof) or expense arises out of or is based upon 
any untrue statement or alleged untrue statement or omission or alleged 
omission made in such registration statement, any such preliminary 
prospectus, final prospectus, summary prospectus, amendment or supplement 
in reliance upon and in conformity with written information furnished to 
the Company by such Indemnified Party.

(b)	Indemnification by the Holders.  The Company may require, as a 
condition to including any Registrable Securities of any person or entity 
in any registration statement filed pursuant to Section 2, that the 
Company shall have received an undertaking reasonably satisfactory to it 
from such person or entity to indemnify and hold harmless (in the same 
manner and to the same extent as set forth in subdivision (a) of this 
Section 6) the Company, each director of the Company, each officer of the 
Company and each other person, if any, who controls the Company within the 
meaning of the Securities Act, with respect to any statement or alleged 
statement in or omission or alleged omission from such registration 
statement, any preliminary prospectus, final prospectus or summary 
prospectus contained therein, or any amendment or supplement thereto, if, 
and only if, such statement or alleged statement or omission or alleged 
omission was made in reliance upon and in conformity with information 
furnished in writing to the Company directly by such person or entity 
specifically for use therein; provided, however, that the obligation of 
any Holder hereunder shall be limited to an amount equal to the proceeds 
received by such Holder upon the sale of Registrable Securities sold in 
the offering covered by such registration.  

(c)	Notices of Claims, etc.  Promptly after receipt by an 
Indemnified Party of notice of the commencement of any action or 
proceeding involving a claim referred to in the preceding subdivisions of 
this Section 6, such Indemnified Party will, if a claim in respect thereof 
is to be made against a party required to provide indemnification (an 
"Indemnifying Party"), give written notice to the latter of the 
commencement of such action, provided, however, that the failure of any 
Indemnified Party to give notice as provided herein shall not relieve the 
Indemnifying Party of its obligation under the preceding subdivisions of 
this Section 6, except to the extent that the Indemnifying Party is 
actually prejudiced by such failure to give notice.  In case any such 
action is brought against an Indemnified Party, unless in such Indemnified 
Party's reasonable judgment a conflict of interest between such 
Indemnified and indemnifying parties may exist in respect of such claim, 
the Indemnifying Party shall 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 liable to such 
Indemnified Party for any legal or other expenses subsequently incurred by 
the latter in connection with the defense thereof other than reasonable 
costs of investigation.  No Indemnifying Party shall consent to entry of 
any judgment or enter into any settlement without the consent of the 
Indemnified Party 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.

(d)	Other Indemnification.  Indemnification similar to that 
specified in the preceding subdivisions of this Section 6 (with 
appropriate modifications) shall be given by the Company and each Holder 
of Registrable Securities included in any registration statement with 
respect to any required registration or other qualification of securities 
under any Federal or state law or regulation of any governmental 
authority, other than the Securities Act.

(e)	Indemnification Payment.  The indemnification required by this 
Section 6 shall be made by periodic payments of the amount thereof during 
the course of the investigation or defense, as and when bills are received 
or expense, loss, damage or liability is incurred.

(f)	Survival of Obligations.  The obligations of the Company and 
of the Holders under this Section 6 shall survive the completion of any 
offering of Registrable Securities under this Agreement.

(g)	Contribution.  If the indemnification provided for in this 
Section 6 is unavailable or insufficient to hold harmless an Indemnified 
Party, then each Indemnifying Party shall contribute to the amount paid or 
payable to such Indemnified Party as a result of the losses, claims, 
damages or liabilities referred to in this Section 6 an amount or 
additional amount, as the case may be, in such proportion as is 
appropriate to reflect the relative fault of the Indemnifying Party or 
parties on the one hand and the Indemnified Party on the other in 
connection with the statements or omissions which resulted in such losses, 
claims, demands or liabilities as well as any other relevant equitable 
considerations.  The relative fault 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 parties on 
the one hand or the Indemnified Party on the other and the parties' 
relative, intent, knowledge, access to information and opportunity to 
correct or prevent such untrue statement or omission.  The amount paid to 
an Indemnified Party as a result of the losses, claims, damages or 
liabilities referred to in the first sentence of this Section 6(g) shall 
be deemed to include any legal or other expenses reasonably incurred by 
such Indemnified Party in connection with investigating or defending any 
action or claim which is the subject of this Section 6.  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.
7.	Covenants Relating to Rule 144.
With a view to making available the benefits of certain rules and 
regulations of the Commission which may at any time permit the sale of 
securities of the Company to the public without registration after such 
time as a public market exists for the Common Stock of the Company, the 
Company agrees:
(a)	to make and keep public information available, as those terms 
are understood and defined in Rule 144 under the Securities Act, at all 
times after the effective date of the first registration under the 
Securities Act filed by the Company for an offering of its securities 
to the general public;
(b)	to use its best efforts to then file with the Commission in a 
timely manner all reports and other documents required of the Company 
under the Securities Act and the Exchange Act, as amended (at any time 
after it has become subject to such reporting requirements); and
(c)	so long as a Holder owns any Registrable Securities, to 
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 (at any time after 90 days after the effective date of the 
first registration statement filed by the Company for an offering of 
its securities to the general public), and of the Securities Act and 
the Exchange Act (at any time after it has become subject to such 
reporting requirements) a copy of the most recent annual or quarterly 
report of the Company, and such other reports and documents of the 
Company as a Holder may reasonably request in availing itself of any 
rule or regulation of the Commission allowing a Holder to sell any such 
securities without registration.
8.	Other Registration Rights.
The Company represents and warrants that it has not granted any 
registration rights to any Person other than as described in the Purchase 
Agreement.  The Company shall not grant to any Person any registration 
rights more favorable than or inconsistent with any of those contained 
herein, so long as any of the registration rights under this Agreement 
remain in effect. 
9.	Miscellaneous.
(a)	Specific Performance.  The parties hereto acknowledge that 
there may be no adequate remedy at law if any party fails to perform any 
of its obligations hereunder and that each party may be irreparably harmed 
by any such failure, and accordingly agree that each party, in addition to 
any other remedy to which it may be entitled at law or in equity, shall be 
entitled to compel specific performance of the obligations of any other 
party under this Agreement in accordance with the terms and conditions of 
this Agreement.

not constitute a part of this Agreement and shall not affect in any way 
the meaning or interpretation of this Agreement.

(e)	Entire Agreement; Amendments.  This Agreement and the other 
writings referred to herein or delivered pursuant hereto which form a part 
hereof contain the entire understanding of the parties with respect to its 
subject matter.  This Agreement supersedes all prior agreements and 
understandings between the parties with respect to its subject matter.  
This Agreement may be amended and the observance of any term of this 
Agreement may be waived (either generally or in a particular instance and 
either retroactively or prospectively) only by a written instrument duly 
executed by the Company and the Requisite Holders.  Each Holder of any

Security to the extent of the securities so transferred or assigned, 
provided that (i) such purchaser, transferee or assignee is an Affiliate 
or beneficial owner of the seller, transferor or assignor, (ii) after

stock dividends or stock splits), or (iii) the seller, transferor or 
assignor does not affirmatively restrict in writing the transfer or 
assignment of rights hereunder with respect to such securities.  However, 
the Company shall not be required to recognize any such purchaser, 
transferee or assignee as a Holder under this Agreement unless and until 
either (i) such person becomes the holder of record of Series A Preferred 
Stock, Warrants, or Registrable Securities or (ii) the Company receives 
written notice of such purchase, transfer or assignment and a written 
agreement by the purchaser, assignee or transferee to be bound by the 
provisions of this Agreement.

(g)	Counterparts.  This Agreement may be executed in two or more 
counterparts, each of which shall be deemed an original, but all of which 
together shall constitute one and the same instrument.

(h)	Stock Splits, Etc. If the Company at any time subdivides (by 
any stock split, stock dividend, recapitalization or otherwise) its 
outstanding shares of Common Stock into a greater number of shares or if 
the outstanding shares of Common Stock shall be combined (by reverse stock 
split or otherwise) into a smaller number of shares, all numbers, 
percentages, computations and the like in this Agreement shall be deemed 
modified as necessary to give appropriate effect to such subdivision or 
combination.

IN WITNESS WHEREOF, the parties have executed this Agreement as of the 
date first written above.
