Investor reaching an agreement as to such amounts was the uncertainty and cost
of litigation regarding the question of actual damages, and (iv) the Company and
the Investor are sophisticated business parties and have been represented by
sophisticated and able legal counsel and negotiated this Agreement at arm's
length.

have sold all the Registrable Securities covered by such Registration Statement
(the "Registration Period"), which Registration Statement (including any
amendments or supplements thereto and prospectuses contained therein) shall not
contain any 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, in
light of the circumstances in which they were made, not misleading.

Statement and the prospectus used in connection with such Registration
Statement, which prospectus is to be filed pursuant to Rule 424 promulgated
under the 1933 Act, as may be necessary to keep such Registration Statement
effective at all times during the Registration Period, and, during such period,
comply with the provisions of the 1933 Act with respect to the disposition of
all Registrable Securities of the Company covered by such Registration Statement
until such time as all of such Registrable Securities shall have been disposed
of in accordance with the intended methods of disposition by the seller or
sellers thereof as set forth in such Registration Statement. In the case of
amendments and supplements to a Registration Statement which are required to be
filed pursuant to this Agreement (including pursuant to this Section 3(b)) by
reason of the Company's filing a report on Form 10-KSB, Form 10-QSB or Form 8-K
or any analogous report under the Securities Exchange Act of 1934, as amended
(the "1934 Act"), the Company shall incorporate such report by reference into
the Registration Statement, if applicable, or shall file such amendments or
supplements with the SEC on the same day on which the 1934 Act report is filed
which created the requirement for the Company to amend or supplement the
Registration Statement.

            (c) The Company shall furnish to each Investor whose Registrable
Securities are included in any Registration Statement, without charge, (i) at

<PAGE>

all documents incorporated therein by reference, all exhibits and each
preliminary prospectus, (ii) ten (10) copies of the final prospectus included in
such Registration Statement and all amendments and supplements thereto (or such
other number of copies as such Investor may reasonably request) and (iii) such
other documents as such Investor may reasonably request from time to time in
order to facilitate the disposition of the Registrable Securities owned by such
Investor.

            (d) The Company shall use its best efforts to (i) register and
qualify the Registrable Securities covered by a Registration Statement under
such other securities or "blue sky" laws of such jurisdictions in the United

jurisdictions, such amendments (including post-effective amendments) and
supplements to such registrations and qualifications as may be necessary to
maintain the effectiveness thereof during the Registration Period, (iii) take
such other actions as may be necessary to maintain such registrations and
qualifications in effect at all times during the Registration Period, and (iv)
take all other actions reasonably necessary or advisable to qualify the

(x) qualify to do business in any jurisdiction where it would not otherwise be
required to qualify but for this Section 3(d), (y) subject itself to general
taxation in any such jurisdiction, or (z) file a general consent to service of

laws of any jurisdiction in the United States or its receipt of actual notice of
the initiation or threat of any proceeding for such purpose.

            (e) As promptly as practicable after becoming aware of such event or
development, the Company shall notify each Investor in writing of the happening
of any event as a result of which the prospectus included in a Registration
Statement, as then in effect, includes an untrue statement of a material fact or
omission to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading (provided that in no event shall such notice contain any
material, nonpublic information), and promptly prepare a supplement or amendment
to such Registration Statement to correct such untrue statement or omission, and
deliver ten (10) copies of such supplement or amendment to each Investor. The
Company shall also promptly notify each Investor in writing (i) when a
prospectus or any prospectus supplement or post-effective amendment has been
filed, and when a Registration Statement or any post-effective amendment has
become effective (notification of such effectiveness shall be delivered to each
Investor by facsimile on the same day of such effectiveness), (ii) of any
request by the SEC for amendments or supplements to a Registration Statement or
related prospectus or related information, and (iii) of the Company's reasonable
determination that a post-effective amendment to a Registration Statement would
be appropriate.

of any stop order or other suspension of effectiveness of a Registration
Statement, or the suspension of the qualification of any of the Registrable
Securities for sale in any jurisdiction within the United States of America and,
if such an order or suspension is issued, to obtain the withdrawal of such order


                                       4

resolution thereof or its receipt of actual notice of the initiation or threat
of any proceeding for such purpose.

independent certified public accountants to underwriters in an underwritten
public offering, and (ii) an opinion, dated as of such date, of counsel
representing the Company for purposes of such Registration Statement, in form,
scope and substance as is customarily given in an underwritten public offering,
addressed to the Investors.

            (h) The Company shall make available for inspection by (i) any
Investor and (ii) one (1) firm of accountants or other agents retained by the
Investors (collectively, the "Inspectors") all pertinent financial and other
records, and pertinent corporate documents and properties of the Company
(collectively, the "Records"), as shall be reasonably deemed necessary by each
Inspector, and cause the Company's officers, directors and employees to supply
all information which any Inspector may reasonably request; provided, however,
that each Inspector shall agree, and each Investor hereby agrees, to hold in
strict confidence and shall not make any disclosure (except to an Investor) or
use any Record or other information which the Company determines in good faith
to be confidential, and of which determination the Inspectors are so notified,
unless (a) the disclosure of such Records is necessary to avoid or correct a
misstatement or omission in any Registration Statement or is otherwise required
under the 1933 Act, (b) the release of such Records is ordered pursuant to a
final, non-appealable subpoena or order from a court or government body of
competent jurisdiction, or (c) the information in such Records has been made
generally available to the public other than by disclosure in violation of this
or any other agreement of which the Inspector and the Investor has knowledge.

Records is sought in or by a court or governmental body of competent
jurisdiction or through other means, give prompt notice to the Company and allow
the Company, at its expense, to undertake appropriate action to prevent
disclosure of, or to obtain a protective order for, the Records deemed
confidential.

or correct a misstatement or omission in any Registration Statement, (iii) the

agreement. The Company agrees that it shall, upon learning that disclosure of
such information concerning an Investor is sought in or by a court or
governmental body of competent jurisdiction or through other means, give prompt
written notice to such Investor and allow such Investor, at the Investor's
expense, to undertake appropriate action to prevent disclosure of, or to obtain
a protective order for, such information.

            (j) The Company shall use its best efforts either to cause all the
Registrable Securities covered by a Registration Statement (i) to be listed on
each securities exchange on which securities of the same class or series issued
by the Company are then listed, if any, if the listing of such Registrable
Securities is then permitted under the rules of such exchange or (ii) the
inclusion for quotation on the National Association of Securities Dealers, Inc.
OTC Bulletin Board for such Registrable Securities. The Company shall pay all
fees and expenses in connection with satisfying its obligation under this
Section 3(j).

denominations or amounts, as the case may be, as the Investors may reasonably
request and registered in such names as the Investors may request.

period beginning not later than the first day of the Company's fiscal quarter
next following the effective date of the Registration Statement.

            (n) The Company shall otherwise use its best efforts to comply with

registration hereunder.

            (o) Within two (2) business days after a Registration Statement

Company shall deliver, and shall cause legal counsel for the Company to deliver,
to the transfer agent for such Registrable Securities (with copies to the
Investors whose Registrable Securities are included in such Registration
Statement) confirmation that such Registration Statement has been declared

<PAGE>

the contrary, the Company shall cause its transfer agent to deliver unlegended
certificates for shares of Common Stock to a transferee of an Investor in

            6. INDEMNIFICATION.

      With respect to Registrable Securities which are included in a
Registration Statement under this Agreement:

            (a) To the fullest extent permitted by law, the Company will, and
hereby does, indemnify, hold harmless and defend each Investor, the directors,
officers, partners, employees, agents, representatives of, and each Person, if
any, who controls any Investor within the meaning of the 1933 Act or the 1934
Act (each, an "Indemnified Person"), against any losses, claims, damages,
liabilities, judgments, fines, penalties, charges, costs, reasonable attorneys'
fees, amounts paid in settlement or expenses, joint or several (collectively,
"Claims") incurred in investigating, preparing or defending any action, claim,
suit, inquiry, proceeding, investigation or appeal taken from the foregoing by
or before any court or governmental, administrative or other regulatory agency,
body or the SEC, whether pending or threatened, whether or not an indemnified
party is or may be a party thereto ("Indemnified Damages"), to which any of them
may become subject insofar as such Claims (or actions or proceedings, whether
commenced or threatened, in respect thereof) arise out of or are based upon: (i)
any untrue statement or alleged untrue statement of a material fact in a
Registration Statement or any post-effective amendment thereto or in any filing
made in connection with the qualification of the offering under the securities
or other "blue sky" laws of any jurisdiction in which Registrable Securities are
offered ("Blue Sky Filing"), or the omission or alleged omission to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading; (ii) any untrue statement or alleged untrue statement of
a material fact contained in any final prospectus (as amended or supplemented,
if the Company files any amendment thereof or supplement thereto with the SEC)
or the omission or alleged omission to state therein any material fact necessary
to make the statements made therein, in light of the circumstances under which
the statements therein were made, not misleading; or (iii) any violation or
alleged violation by the Company of the 1933 Act, the 1934 Act, any other law,
including, without limitation, any state securities law, or any rule or
regulation there under relating to the offer or sale of the Registrable
Securities pursuant to a Registration Statement (the matters in the foregoing
clauses (i) through (iii) being, collectively, "Violations"). The Company shall
reimburse the Investors and each such controlling person promptly as such
expenses are incurred and are due and payable, for any legal fees or
disbursements or other reasonable expenses incurred by them in connection with
investigating or defending any such Claim. Notwithstanding anything to the
contrary contained herein, the indemnification agreement contained in this
Section 6(a): (x) shall not apply to a Claim by an Indemnified Person arising
out of or based upon a Violation which occurs in reliance upon and in conformity


                                       7
<PAGE>

with information furnished in writing to the Company by such Indemnified Person
expressly for use in connection with the preparation of the Registration
Statement or any such amendment thereof or supplement thereto; (y) shall not be
available to the extent such Claim is based on a failure of the Investor to
deliver or to cause to be delivered the prospectus made available by the
Company, if such prospectus was timely made available by the Company pursuant to
Section 3(c); and (z) shall not apply to amounts paid in settlement of any Claim
if such settlement is effected without the prior written consent of the Company,
which consent shall not be unreasonably withheld. Such indemnity shall remain in
full force and effect regardless of any investigation made by or on behalf of
the Indemnified Person and shall survive the transfer of the Registrable
Securities by the Investors pursuant to Section 9 hereof.

            (b) In connection with a Registration Statement, each Investor
agrees to severally and not jointly indemnify, hold harmless and defend, to the
same extent and in the same manner as is set forth in Section 6(a), the Company,
each of its directors, each of its officers, employees, representatives, or
agents and each Person, if any, who controls the Company within the meaning of
the 1933 Act or the 1934 Act (each an "Indemnified Party"), against any Claim or
Indemnified Damages to which any of them may become subject, under the 1933 Act,
the 1934 Act or otherwise, insofar as such Claim or Indemnified Damages arise
out of or is based upon any Violation, in each case to the extent, and only to
the extent, that such Violation occurs in reliance upon and in conformity with
written information furnished to the Company by such Investor expressly for use
in connection with such Registration Statement; and, subject to Section 6(d),
such Investor will reimburse any legal or other expenses reasonably incurred by
them in connection with investigating or defending any such Claim; provided,
however, that the indemnity agreement contained in this Section 6(b) and the
agreement with respect to contribution contained in Section 7 shall not apply to
amounts paid in settlement of any Claim if such settlement is effected without
the prior written consent of such Investor, which consent shall not be
unreasonably withheld; provided, further, however, that the Investor shall be
liable under this Section 6(b) for only that amount of a Claim or Indemnified
Damages as does not exceed the net proceeds to such Investor as a result of the
sale of Registrable Securities pursuant to such Registration Statement. Such
indemnity shall remain in full force and effect regardless of any investigation
made by or on behalf of such Indemnified Party and shall survive the transfer of
the Registrable Securities by the Investors pursuant to Section 9.
Notwithstanding anything to the contrary contained herein, the indemnification
agreement contained in this Section 6(b) with respect to any prospectus shall
not inure to the benefit of any Indemnified Party if the untrue statement or
omission of material fact contained in the prospectus was corrected and such new
prospectus was delivered to each Investor prior to such Investor's use of the
prospectus to which the Claim relates.

            (c) Promptly after receipt by an Indemnified Person or Indemnified
Party under this Section 6 of notice of the commencement of any action or
proceeding (including any governmental action or proceeding) involving a Claim,
such Indemnified Person or Indemnified Party shall, if a Claim in respect
thereof is to be made against any indemnifying party under this Section 6,
deliver to the indemnifying party a written notice of the commencement thereof,
and the indemnifying party shall have the right to participate in, and, to the
extent the indemnifying party so desires, jointly with any other indemnifying


                                       8
<PAGE>

party similarly noticed, to assume control of the defense thereof with counsel
mutually satisfactory to the indemnifying party and the Indemnified Person or
the Indemnified Party, as the case may be; provided, however, that an
Indemnified Person or Indemnified Party shall have the right to retain its own
counsel with the fees and expenses of not more than one (1) counsel for such
Indemnified Person or Indemnified Party to be paid by the indemnifying party,
if, in the reasonable opinion of counsel retained by the indemnifying party, the
representation by such counsel of the Indemnified Person or Indemnified Party
and the indemnifying party would be inappropriate due to actual or potential
differing interests between such Indemnified Person or Indemnified Party and any
other party represented by such counsel in such proceeding. The Indemnified
Party or Indemnified Person shall cooperate fully with the indemnifying party in
connection with any negotiation or defense of any such action or claim by the
indemnifying party and shall furnish to the indemnifying party all information
reasonably available to the Indemnified Party or Indemnified Person which
relates to such action or claim. The indemnifying party shall keep the
Indemnified Party or Indemnified Person fully apprised at all times as to the
status of the defense or any settlement negotiations with respect thereto. No
indemnifying party shall be liable for any settlement of any action, claim or
proceeding effected without its prior written consent; provided, however, that
the indemnifying party shall not unreasonably withhold, delay or condition its
consent. No indemnifying party shall, without the prior written consent of the
Indemnified Party or Indemnified Person, consent to entry of any judgment or
enter into any settlement or other compromise which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
Indemnified Party or Indemnified Person of a release from all liability in
respect to such claim or litigation. Following indemnification as provided for
hereunder, the indemnifying party shall be subrogated to all rights of the
Indemnified Party or Indemnified Person with respect to all third parties, firms
or corporations relating to the matter for which indemnification has been made.
The failure to deliver written notice to the indemnifying party within a
reasonable time of the commencement of any such action shall not relieve such
indemnifying party of any liability to the Indemnified Person or Indemnified
Party under this Section 6, except to the extent that the indemnifying party is
prejudiced in its ability to defend such action.

            (d) 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 Indemnified Damages are incurred.

            (e) The indemnity agreements contained herein shall be in addition
to (i) any cause of action or similar right of the Indemnified Party or
Indemnified Person against the indemnifying party or others, and (ii) any
liabilities the indemnifying party may be subject to pursuant to the law.

            7. CONTRIBUTION.

      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 Section 6 to the fullest extent permitted by law; provided, however, that:
(i) no seller of Registrable Securities guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the 1933 Act) shall be entitled to
contribution from any seller of Registrable Securities who was not guilty of
fraudulent misrepresentation; and (ii) contribution by any seller of Registrable
Securities shall be limited in amount to the net amount of proceeds received by
such seller from the sale of such Registrable Securities.

the Company remains subject to such requirements (it being understood that
nothing herein shall limit the Company's obligations under Section 4(c) of the
Securities Purchase Agreement) and the filing of such reports and other
documents as are required by the applicable provisions of Rule 144; and

            (c) furnish to each Investor so long as such Investor owns

Company, and (iii) such other information as may be reasonably requested to
permit the Investors to sell such securities pursuant to Rule 144 without
registration.

            9. ASSIGNMENT OF REGISTRATION RIGHTS.

      The rights under this Agreement shall be automatically assignable by the
Investors to any transferee of all or any portion of Registrable Securities if:
(i) the Investor agrees in writing with the transferee or assignee to assign
such rights, and a copy of such agreement is furnished to the Company within a
reasonable time after such assignment; (ii) the Company is, within a reasonable
time after such transfer or assignment, furnished with written notice of (a) the
name and address of such transferee or assignee, and (b) the securities with
respect to which such registration rights are being transferred or assigned;
(iii) at or before the time the Company receives the written notice contemplated

requirements of the Securities Agreement.

            10. AMENDMENT OF REGISTRATION RIGHTS.

or prospectively), only with the written consent of the Company and Investors
who then hold at least two-thirds (2/3) of the Registrable Securities. Any
amendment or waiver effected in accordance with this Section 10 shall be binding
upon each Investor and the Company. No such amendment shall be effective to the

extent that it applies to fewer than all of the holders of the Registrable
Securities. No consideration shall be offered or paid to any Person to amend or
consent to a waiver or modification of any provision of any of this Agreement
unless the same consideration also is offered to all of the parties to this
Agreement.

            11. MISCELLANEOUS.

Securities, the Company shall act upon the basis of instructions, notice or
election received from the registered owner of such Registrable Securities.

            (c) Failure of any party to exercise any right or remedy under this
Agreement or otherwise, or delay by a party in exercising such right or remedy,

action or proceeding is improper. Each party hereby irrevocably waives personal
service of process and consents to process being served in any such suit, action
or proceeding by mailing a copy thereof to such party at the address for such
notices to it under this Agreement and agrees that such service shall constitute

herein shall be deemed to limit in any way any right to serve process in any
manner permitted by law. If any provision of this Agreement shall be invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
affect the validity or enforceability of the remainder of this Agreement in that
jurisdiction or the validity or enforceability of any provision of this
Agreement in any other jurisdiction. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY
RIGHT IT MAY HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION

      Re:

Ladies and Gentlemen:

      We are counsel to ______________, a __________ corporation (the
"Company"), and have represented the Company in connection with that certain
Securities Purchase Agreement (the "Purchase Agreement") entered into by and
among the Company and the investors named therein (collectively, the
"Investors") pursuant to which the Company issued to the Investors shares of its
Common Stock, par value $___ per share (the "Common Stock"). Pursuant to the
Purchase Agreement, the Company also has entered into a Registration Rights
Agreement with the Investors (the "Registration Rights Agreement") pursuant to
which the Company agreed, among other things, to register the Registrable
Securities (as defined in the Registration Rights Agreement) under the
Securities Act of 1933, as amended (the "1933 Act"). In connection with the
Company's obligations under the Registration Rights Agreement, on ____________
____, the Company filed a Registration Statement on Form ________ (File No.
333-_____________) (the "Registration Statement") with the Securities and
Exchange SEC (the "SEC") relating to the Registrable Securities which names each
of the Investors as a selling stockholder there under.

      In connection with the foregoing, we advise you that a member of the SEC's
staff has advised us by telephone that the SEC has entered an order declaring
the Registration Statement effective under the 1933 Act at [ENTER TIME OF
EFFECTIVENESS] on [ENTER DATE OF EFFECTIVENESS] and we have no knowledge, after
telephonic inquiry of a member of the SEC's staff, that any stop order
suspending its effectiveness has been issued or that any proceedings for that
purpose are pending before, or threatened by, the SEC and the Registrable
Securities are available for resale under the 1933 Act pursuant to the
Registration Statement.

                                            Very truly yours,


                                            By:
                                                --------------------------------
