                                    DEBENTURE

                                   TCPI, INC.

                          2000 6% Convertible Debenture

                                      Due:

No.000                                                            $

         This Debenture is issued by TCPI, Inc., (the "Company") to [ ]
(together with its successors and assigns, the "Holder") pursuant to exemptions
from registration under the U.S. Securities Act of 1933, as amended.

                                    ARTICLE I

         1.01 Principal and Interest. For value received, on ________, 2000 (the
"Maturity Date"), the Company hereby promises to pay to the order of the Holder,
GMF Holdings, in lawful money of the United States of America and in immediately
available fund the principal sum of $ [ ] together with interest on the unpaid
principal of this Debenture at the rate of 6% per year (computed on the basis of
a 365 day year and the actual days elapsed) from the date of this Debenture
until paid.

         1.02. Conversion. The Holder is entitled, at its option, to convert at
any time and from time to time, until payment in full of this Debenture, all or
any part of the principal amount of the Debenture, plus accrued interest, into
shares (the "Conversion Shares") of the Company's common stock, $0. 001 par

                                        1
<PAGE>

value ("Common Stock"), at the price per share (the "Conversion Price") equal to
either (i) $1.40 or (ii) 90% of the lowest closing bid prices of the Common
Stock on the Principal market quoted by Bloomberg L.P. (the "Closing Bid Price")
for the twenty (20) trading days immediately preceding the conversion date (the
"Conversion Price"). As used herein, "Principal Market" shall mean the Nasdaq
Bulletin Board System, Nasdaq Small Cap Market, Nasdaq National Market, or
American Stock Exchange. If the Common Stock is not traded on a Principal
Market, the Closing Bid Price shall mean, the reported Closing Bid Price for the
Common Stock, as furnished by the National Association of Securities Dealers,
Inc., for the applicable periods. No fraction of shares or scrip representing
fractions of shares will be issued on conversion, but the number of shares
issuable shall be rounded to the nearest whole share. To convert this Debenture,
the holder hereof shall deliver written notice thereof, substantially in the
form of Exhibit A to this Debenture, with appropriate insertions (the
"Conversion Notice"), to the Company at its address set forth above. The date
upon which the conversion shall be effective (the "Conversion Date") shall be
deemed to be the date set forth in the Conversion Notice, provided that the
Company delivers the Conversion Shares within three (3) business days after
receipt of a Conversion Notice, otherwise, the holder shall have the right to
revoke the Conversion Notice, or to specify the date on which it actually
receives the Conversion Shares as the Conversion Date.

         1.02 Reservation of Common Stock. The Company shall reserve and keep
available out of its authorized but unissued shares of Common Stock, solely for
the purpose of effecting the conversion of this Debenture, such number of shares
of Common Stock as shall from time to time be sufficient to effect such
conversion, based upon the Conversion Price. If at any time the Company does not
have a sufficient number of Conversion Shares authorized and available, then the
Company shall call and hold a special meeting of its stockholders within 120
days of that time for the sole purpose of increasing in the number of authorized
shares of Common Stock.

         1.03 Registration Rights. The Company is obligated to register the
resale of the Conversion Shares under the Securities Act of 1933, as amended,
pursuant to the terms of a Registration Rights Agreement between the Company and
the Holder of even date herewith.

         1.04 Interest Payments. The interest so payable will be paid at the
time of maturity or conversion to the person in whose name this Debenture is
registered. At the time such interest is payable, the Company, in its sole
discretion, may elect to pay interest in cash (via wire transfer or certified
funds) or in the form of Common Stock. In the event of default, as described in
Article III Section 3.01 hereunder, the Holder, may elect that the interest be
paid in cash (via wire transfer or certified funds) or in the form of Common
Stock. If paid in the form of Common Stock, the amount of stock to be issued
will be calculated as follows: the value of the stock shall be the Closing Bid
Price on: (i) the date the interest payment is due; or (ii) if the interest
payment is not made when due, the date the interest payment is made. A number of
shares of Common Stock with a value equal to the amount of interest due shall be
issued. No fractional shares will be issued; therefore, in the event that the
value of the Common Stock per share does not equal the total interest due, the
Company will pay the balance in cash.

         1.05 Paying Agent and Registrar. Initially, the Company will act as
paying agent and registrar. The Company may change any paying agent, registrar,

                                        2
<PAGE>

or Company-registrar by giving the Holder not less than 10 days' written notice
of its election to do so, specifying the name, address, telephone number and
facsimile number of the Paying Agent or Registrar. The Company may act in any
such capacity.

         1.06 Subordinated Nature of Debenture. This Debenture and all payments
hereon, including principal or interest, shall be subordinate and junior in
right of payment to all Company Debt (as defined hereinafter), but only to the
extent set forth as follows:

         (a) upon the maturity of any Company Debt, or any installment thereof
then due by lapse of time, acceleration or otherwise, all Company Debt then due
shall first be paid in full (or provision made for payment in full thereof)
before any additional payment on account of principal or interest is made on
this Debenture; and

         (b) in the event of any insolvency or bankruptcy proceedings affecting
the Company, or any receivership, liquidation, reorganization or other similar
proceedings affecting the Company, and, in the event of any proceedings for
voluntary liquidation, dissolution or other winding up of the Company, whether
or not involving insolvency or bankruptcy, then the holders of Company Debt
shall be entitled to receive payment in full of all principal of and interest on
all Company Debt before the holder of this Debenture is entitled to receive any
payment on account of principal, interest or premium on this Debenture.

         The provisions of the preceding paragraphs are solely for the purpose
of defining the relative rights of the holders of Company Debt on the one hand
and the holder of this Debenture on the other hand and nothing herein shall
impair, as between the Company and the holder of this Debenture, the obligation
of the Company, which is unconditional and absolute, to pay the holder of this
Debenture the principal, interest and premiums hereon in accordance with its
terms, nor shall anything herein prevent the holder of this Debenture from
exercising all remedies otherwise permitted by law or hereunder upon default
hereunder, subject to the relative rights of the holders of Company Debt
expressed in the preceding paragraphs.

         For the purpose of this Notice, the term "Company Debt" shall mean and
include current bank debt and all indebtedness incurred by the Company
subsequent to the date hereof, other than indebtedness incurred to any officer,
director or other person who has beneficial ownership of 10% or more of the
Company's issued and outstanding shares of Common Stock.

                                   ARTICLE II

         2.01 Amendments and Waiver of Default. The Debenture may be amended
with the consent of the Holder. Without the consent of the Holder, the Debenture
may be amended to cure any ambiguity, defect or inconsistency, to provide for
assumption of the Company obligations to the Holder or to make any change that
does not adversely affect the rights of the Holder.

         3.02 Failure to Issue Unrestricted Common Stock. As indicated in
Article III Section

Rights Agreement shall be deemed an Event of Default, which if not cured within
ten (10) days, shall entitle the Investor(s) accelerated full repayment of all
debentures outstanding. The Company acknowledges that failure to honor a Notice
of Conversion shall cause hardship to the Investor(s).

                                   ARTICLE IV

having given effect to such conversion, the Holder shall be or shall be deemed
to be the beneficial owner of 10% or more of the then outstanding Common Stock
within the meaning or for the purposes of Section 13(d) or 13(g) of the U.S.
Securities Exchange Act of 1934, as amended, or as the term "beneficial owner"
is defined in Rule 13d-3 of the U.S. Securities and Exchange Commission or
otherwise.

outstanding shares of Common Stock, or shall issue a stock dividend on the

conditions of this Agreement, the Company shall prepare and, within sixty (60)
calendar days following the date of receipt of final proceeds (the "Filing

Registration Statement is not filed.

                  In the event the Registration Statement is not declared
effective by the SEC by the applicable Scheduled Effective Deadline because of

<PAGE>

         In addition if the Registration Statement is not declared effective by
the Commission by the applicable Scheduled Effective Deadline, or if after the
Registration Statement has been declared effective by the Commission, sales
cannot be made pursuant to the Registration Statement (whether because of a
failure to keep the Registration Statement effective, to disclose such
information as is necessary for sales to be made pursuant to the Registration
Statement, to register sufficient shares of Common Stock or otherwise), then, as
partial relief for the damages to any holder by reason of any such delay in or
reduction of its ability to sell the underlying shares of Common Stock (which
remedy shall not be exclusive of any other remedies at law or in equity), the
Company will pay liquidated damages to the Investor in immediately available
funds into an account designated by the Investor an amount equal to two percent
(2%) of the aggregate purchase price of all of the Registrable Securities then
held by the Investor for each thirty (30) calendar day period (prorated for
partial periods) of such Ineffective Period. The payments required by this
Section 1.1(d) shall be made on the first trading day after the expiration of an
Ineffective Period (or if an Ineffective Period shall last more than thirty (30)
calendar days, the expiration of each additional thirty (30) calendar day period
of an Ineffective Period). As used herein, "Ineffective Period shall mean any
period of time following the Scheduled Effective Deadline during which the
Company's Registration Statement covering the Registrable Securities is not
effective. Notwithstanding the foregoing the Company shall not be required to
pay liquidated damages to any Investor in connection with any Ineffective Period
commencing upon the filing of a post-effective amendment to such Registration
Statement and ending upon the date on which such post effective amendment is
declared effective by the Commission.

                   (d) Liquidated Damages. The Company and the Investor hereto
acknowledge and agree that the sums payable under subsections 1(c) or 1(d) above
shall constitute liquidated damages and not penalties. The parties further
acknowledge that (i) the amount of loss or damages likely to be incurred is
incapable or is difficult to precisely estimate, (ii) the amounts specified in
such subsections bear a reasonable relationship to, and are not plainly or
grossly disproportionate to the probable loss likely to be incurred in
connection with any failure by the Company to obtain or maintain the
effectiveness of a Registration Statement, (iii) one of the reasons for the
Company and the 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.

                                   ARTICLE II
                             REGISTRATION PROCEDURES

         Section 2.1 Filings; Information. The Company will effect the
registration and sale of the Registrable Securities in accordance with the
intended methods of disposition thereof. Without limiting the foregoing, the
Company in each such case will do the following as expeditiously as possible,
but in no event later than the deadline, if any, prescribed therefore in this
Agreement:

                  (a) The Company shall (i) prepare and file with the Commission
a Registration Statement on Form S-1 or S-2 (or, if the Company is then
eligible, Form S-3) within sixty (60) calendar days from the date hereof (if use
of such form is then available to the Company pursuant to the rules of the
Commission and, if not, on such other form promulgated by the Commission for
which the Company then qualifies, that counsel for the Company shall deem
appropriate and which form shall be available for the sale of the Registrable
Securities to be registered there under in accordance with the provisions of
this Agreement and in accordance with the intended method of distribution of
such Registrable Securities); (ii) use commercially reasonable efforts to cause
such filed Registration Statement to become effective within one hundred and
twenty (120) days of the date hereof and remain effective during the period set
forth in Section 1.1(b) hereof (pursuant to Rule 415 under the Securities Act or
otherwise); (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 for
the time period prescribed by Section 1.1(b); and (iv) comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such Registration Statement during such period in
accordance with the intended methods of disposition by the Investor set forth in
such Registration Statement.

                  (b) The Company shall file all necessary amendments and
supplements to any Registration Statement in order to effectuate the purpose of
this Agreement and the Securities Purchase Agreement.

                  (c) No later than twenty four (24) hours prior to filing any
amendment or supplement to the Initial Registration Statement or any subsequent
Registration Statement or prospectus, or any amendment or supplement thereto
(excluding, in each case, amendments deemed to result from the filing of
documents incorporated by reference therein), or such shorter period as is
reasonable under the circumstances, the Company shall deliver to the Investor
and one firm of counsel representing the Investor, in accordance with the notice
provisions of Section 4.8, copies of such Registration Statement as proposed to
be filed, together with exhibits thereto, which documents will be subject to
review by the Investor and such counsel, and thereafter deliver to the Investor
and such counsel, in accordance with the notice provisions of Section 4.8, such
number of copies of the Registration Statement, each amendment and supplement
thereto (in each case including all exhibits thereto), the prospectus included
in such Registration Statement (including each preliminary prospectus) and such
other documents or information as the Investor or counsel may reasonably request
in order to facilitate the disposition of the Registrable Securities.

                  (d) The Company shall deliver, in accordance with the notice
provisions of Section 4.8, to each seller of Registrable Securities covered by a
Registration Statement such number of conformed copies of such Registration
Statement and of each amendment and supplement thereto (in each case including
all exhibits and documents incorporated by reference), such number of copies of
the prospectus contained in any Registration Statement (including each
preliminary prospectus and any summary prospectus) and any other prospectus
filed under Rule 424 promulgated under the Securities Act relating to such
seller's Registrable Securities, and such other documents, as such seller may
reasonably request to facilitate the disposition of its Registrable Securities.

                  (e) After the filing of a Registration Statement, the Company
shall promptly notify the Investor of any stop order issued or threatened by the
Commission in connection therewith and take all reasonable actions required to
prevent the entry of such stop order or to remove it if entered.

                                       5

<PAGE>

                  (f) The Company shall use its commercially reasonable efforts
to (i) register or qualify the Registrable Securities under such other
securities or blue sky laws of such jurisdictions in the United States as the
Investor may reasonably request in light of its intended plan of distribution
and (ii) cause the Registrable Securities to be registered with or approved by
such other governmental agencies or authorities in the United States as may be
necessary by virtue of the business and operations of the Company and do any and
all other acts and things that may be reasonably necessary or advisable to
enable the Investor to consummate the disposition of the Registrable Securities
in light of its intended plan of distribution; provided, however, that the
Company will not be required to qualify generally to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
paragraph (f), subject itself to taxation in any such jurisdiction, or consent
or subject itself to general service of process in any such jurisdiction.

                  (g) The Company shall immediately notify the Investor upon the
occurrence of any of the following events in respect of a Registration Statement
or related prospectus in respect of an offering of Registrable Securities: (i)
receipt of any request by the Commission or any other federal or state
governmental authority for additional information, amendments or supplements to
such Registration Statement or related prospectus; (ii) the issuance by the
Commission or any other federal or state governmental authority of any stop
order suspending the effectiveness of such Registration Statement or
notification of the initiation of any proceedings for that purpose; (iii)
receipt of any notification with respect to the suspension of the qualification
or exemption from qualification of any of the Registrable Securities for sale in
any jurisdiction or the initiation or threatening of any proceeding for such
purpose; (iv) the happening of any event that makes any statement made in such
Registration Statement or related prospectus or any document incorporated or
deemed to be incorporated therein by reference untrue in any material respect or
that requires the making of any changes in such Registration Statement, related
prospectus or documents so that, in the case of such Registration Statement, it
will not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading, in the light of the circumstances under which they were
made, and that in the case of the related prospectus, it will not contain any
untrue statement of a material fact or omit to state any material fact required
to be stated therein or necessary to make the statements therein, in the light
of the circumstances under which they were made, not misleading; and (v) the
Company's reasonable determination that a post-effective amendment to such
Registration Statement would be appropriate, and the Company will promptly make
available to the Investor any such supplement or amendment to the related
prospectus.

                  (h) The Company shall enter into customary agreements and take
such other customary actions as are reasonably required in order to expedite or
facilitate the disposition by the Investor of such Registrable Securities
(whereupon the Investor may, at its option, require that any or all of the
representations, warranties and covenants of the Company also be made to and for
the benefit of the Investor).

<PAGE>

                  (i) The Company shall make available to the Investor (and will
deliver to Investor's counsel), subject to restrictions imposed by the United
States federal government or any agency or instrumentality thereof, copies of
all correspondence between the Commission and the Company, its counsel or its
auditors and will also make available for inspection by the Investor and any
attorney, accountant or other professional retained by the Investor
(collectively, the "Inspectors"), all financial and other records, pertinent
corporate documents and properties of the Company (collectively, the "Records")
as shall be reasonably necessary to enable them to exercise their due diligence
responsibility, and cause the Company's officers and employees to supply all
information reasonably requested by any Inspectors in connection with a
Registration Statement. Records that the Company determines, in good faith, to
be confidential and that it notifies the Inspectors are confidential shall not
be disclosed by the Inspectors unless (i) the disclosure of such Records is
necessary to avoid or correct a misstatement or omission in any Registration
Statement or (ii) the disclosure or release of such Records is requested or
required pursuant to oral questions, interrogatories, requests for information
or documents or a subpoena or other order from a court of competent jurisdiction
or other legal process; provided, however, that prior to any disclosure or
release pursuant to clause (ii), the Inspectors shall provide the Company with
prompt notice of any such request or requirement so that the Company may seek an
appropriate protective order or waive such Inspectors' obligation not to
disclose such Records; and, provided, further, that if failing the entry of a
protective order or the waiver by the Company permitting the disclosure or
release of such Records, the Inspectors, upon advice of counsel, are compelled
to disclose such Records, the Inspectors may disclose that portion of the
Records that counsel has advised the Inspectors that the Inspectors are
compelled to disclose. The Investor agrees that information obtained by it as a
result of such inspections (not including any information obtained from a third
party who, insofar as is known to the Investor after reasonable inquiry, is not
prohibited from providing such information by a contractual, legal or fiduciary
obligation to the Company) shall be deemed confidential and shall not be used by
it as the basis for any market transactions in the securities of the Company
unless and until such information has been made generally available to the
public. The Investor further agrees that it will, upon learning that disclosure
of such Records is sought in a court of competent jurisdiction, give notice to
the Company and allow the Company, at its expense, to undertake appropriate
action to prevent disclosure of the Records deemed confidential.

                  (j) The Company shall otherwise comply with all applicable
rules and regulations of the Commission, including, without limitation,
compliance with applicable reporting requirements under the Exchange Act.

                  (k) The Company may require the Investor to promptly furnish
in writing to the Company such information as may be legally required in
connection with such registration including, without limitation, all such
information as may be requested by the Commission or the National Association of
Securities Dealers, Inc. ("NASD"). The Investor agrees to provide such
information requested in connection with such registration within five (5)
calendar days after receiving such written request, or such shorter period as is
reasonable under the circumstances, and the Company shall not be responsible for
any delays in obtaining or maintaining the effectiveness of any Registration
Statement caused by the Investor's failure to timely provide such information.

<PAGE>

                  (l) The Company shall use its best efforts either: (i) to
secure the inclusion for quotation on The Nasdaq Stock Market Inc.'s National
Market or OTC Bulletin Board Bulletin for such Resgistrable Securities, or (ii)
if, despite the Company's best efforts to satisfy the preceding clause (i), the
Company is unsuccessful in satisfying the preceding clause (i), to secure the
inclusion for quotation in the "pink sheets" for such Registrable Securities,
and, without limiting the generality of the foregoing, in the case of clause (i)
or (ii), to arrange for at least two market makers to register with the NASD, as
such with respect to such Registrable Securities. The Company shall pay all fees
and expenses in connection with satisfying its obligation under this Section
2(l).

         Section 2.2 Registration Expenses. In connection with each Registration
Statement, the Company shall pay all registration expenses incurred in
connection with the registration thereunder (the "Registration Expenses"),
including, without limitation: (a) all registration, filing, securities exchange
listing and fees required by the NASD, (b) all registration, filing,
qualification and other fees and expenses of compliance with securities or blue
sky laws (including reasonable fees and disbursements of counsel for the
Company), (c) all word processing, duplicating, printing, messenger and delivery
expenses, (d) the Company's internal expenses (including, without limitation,
all salaries and expenses of its officers and employees performing legal or
accounting duties), and (e) reasonable fees and disbursements of counsel for the
Company and customary fees and expenses for independent certified public
accountants retained by the Company; but excluding underwriting fees, discounts,
transfer taxes or commissions, if any, attributable to the sale of the
Registrable Securities, which shall be payable by each holder of Registrable
Securities pro rata on the basis of the number of Registrable Securities of each
holder that are included under this Agreement.

                                   ARTICLE III
                        INDEMNIFICATION AND CONTRIBUTION

         Section 3.1       Indemnification.

                  (a) Indemnification by the Company. The Company agrees to
indemnify and hold harmless the Investor, its partners, affiliates, officers,
directors, employees, counsel and duly authorized agents, and each Person or
entity, if any, who controls the Investor within the meaning of Section 15 of
the Securities Act or Section 20 of the Exchange Act, together with the
partners, Affiliates, officers, directors, employees, counsel and duly
authorized agents of such controlling Person or entity (collectively, the "
Controlling Persons"), from and against any loss, claim, damage, liability,
costs and expenses (including, without limitation, reasonable attorneys' fees
and disbursements and costs and expenses of investigating and defending any such
claim) (collectively, "Damages"), joint or several, and any action or proceeding
in respect thereof to which the Investor, its partners, Affiliates, officers,
directors, employees and duly authorized agents, and any Controlling Person, may
become subject under the Securities Act or otherwise, as incurred, insofar as
such Damages (or actions or proceedings in respect thereof) arise out of, or are
based upon, any untrue statement or alleged untrue statement of a material fact
contained in any Registration Statement, preliminary prospectus or prospectus
relating to the Registrable Securities or arises out of, or are based upon, 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 in
light of the circumstances under which they were made, except insofar as any
such untrue statement, alleged untrue statement, omission or alleged omission is
made in reliance upon and in conformity with written information

                                       8

<PAGE>

furnished to the Company by the Investor which is specifically intended by the
Investor for use in the preparation of any such Registration Statement,
preliminary prospectus or prospectus, and shall reimburse the Investor, its
partners, Affiliates, officers, directors, employees, counsel and duly
authorized agents, and each such Controlling Person, for any legal and other
expenses reasonably incurred by the Investor, its partners, Affiliates,
officers, directors, employees, counsel and duly authorized agents, or any such
Controlling Person, as incurred, in investigating or defending or preparing to
defend against any such Damages or actions or proceedings; provided, however,
that the Company shall not be liable to the Investor to the extent that any such
Damages arise out of or are based upon an untrue statement or omission made in
any preliminary prospectus if (i) the Investor failed to send or deliver a copy
of the final prospectus delivered by the Company to the Investor with or prior
to the delivery of written confirmation of the sale by the Investor to the
Person asserting the claim from which such Damages arise, or (ii) the final
prospectus would have corrected such untrue statement or alleged untrue
statement or such omission or alleged omission.

                  (b) Indemnification by the Investor. The Investor agrees to
indemnify and hold harmless the Company, its Affiliates, officers, directors,
employees, counsel and duly authorized agents, and each Controlling Persons of
the Company, from and against any and all Damages, joint or several, and any
action or proceeding in respect thereof to which the Investor, its partners,
Affiliates, officers, directors, employees, counsel and duly authorized agents,
and any such Controlling Person, may become subject under the Securities Act or
otherwise, as incurred, insofar as such Damages (or actions or proceedings in
respect thereof) arise out of, or are based upon, any untrue statement or
alleged untrue statement of a material fact contained in any Registration
Statement, preliminary prospectus or prospectus relating to the Registrable
Securities or arises out of, or are based upon, 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 in light of the circumstances under
which they were made, but only to the extent that any such untrue statement,
alleged untrue statement, omission or alleged omission is made in reliance upon
and in conformity with written information furnished to the Company by the
Investor which is specifically intended by the Investor for use in the
preparation of any such Registration Statement, preliminary prospectus or
prospectus, and shall reimburse the Company, its partners, Affiliates, officers,
directors, employees, counsel and duly authorized agents, and each such
Controlling Person, for any legal and other expenses reasonably incurred by the
Investor, its partners, Affiliates, officers, directors, employees, counsel and
duly authorized agents, or any such Controlling Person, as incurred, in
investigating or defending or preparing to defend against any such Damages or
actions or proceedings.

         Section 3.2 Conduct of Indemnification Proceedings. Promptly after
receipt by any person or entity in respect of which indemnity may be sought
pursuant to Section 3.1 (an "Indemnified Party") of notice of any claim or the
commencement of any action, the Indemnified Party shall, if a claim in respect
thereof is to be made against the person or entity against whom such indemnity
may be sought (the "Indemnifying Party"), notify the Indemnifying Party in
writing of the claim or the commencement of such action. In the event an
Indemnified Party shall fail to give such notice as provided in this Section 3.2
and the Indemnifying Party to whom notice was not given was unaware of the
proceeding to which such notice would have related and was prejudiced by the
failure to give such notice, the indemnification provided for in Section 3.1
shall be reduced to the extent of any actual prejudice resulting from such
failure to so notify the Indemnifying Party; provided,

                                       9

<PAGE>

however, that the failure to notify the Indemnifying Party shall not relieve the
Indemnifying Party from any liability that it may have to an Indemnified Party
otherwise than under Section 3.1. If any such claim or action shall be brought
against an Indemnified Party, and it shall notify the Indemnifying Party
thereof, the Indemnifying Party shall be entitled to participate therein, and,
to the extent that it wishes, jointly with any other similarly notified
Indemnifying Party, to assume the defense thereof with counsel reasonably
satisfactory to the Indemnified Party. After notice from the Indemnifying Party
to the Indemnified Party of its election to assume the defense of such claim or
action, the Indemnifying Party shall not be liable to the Indemnified Party for
any legal or other expenses subsequently incurred by the Indemnified Party in
connection with the defense thereof other than reasonable costs of
investigation; provided, however, that the Indemnified Party shall have the
right to employ separate counsel to represent the Indemnified Party and its
Controlling Persons who may be subject to liability arising out of any claim in
respect of which indemnity may be sought by the Indemnified Party against the
Indemnifying Party, but the fees and expenses of such counsel shall be for the
account of such Indemnified Party, unless (i) the Indemnifying Party and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) in the reasonable judgment of the Indemnifying Party and the Indemnified
Party, representation of both parties by the same counsel would be inappropriate
due to actual or potential conflicts of interest between them, it being
understood, however, that the Indemnifying Party shall not, in connection with
any one such claim or action or separate but substantially similar or related
claims or actions in the same jurisdiction arising out of the same general
allegations or circumstances, be liable for the fees and expenses of more than
one separate firm of attorneys (together with appropriate local counsel) at any
time for all Indemnified Parties, or for fees and expenses that are not
reasonable. No Indemnifying Party shall, without the prior written consent of
the Indemnified Party, effect any settlement of any claim or pending or
threatened proceeding in respect of which the Indemnified Party is or could have
been a party and indemnity is sought hereunder by such Indemnified Party, unless
such settlement includes an unconditional release of such Indemnified Party from
all liability arising out of such claim or proceeding. Whether or not the
defense of any claim or action is assumed by the Indemnifying Party, such
Indemnifying Party will not be subject to any liability for any settlement made
without its consent, which consent will not be unreasonably withheld.

         Section 3.3 Other Indemnification. Indemnification similar to that
specified in the preceding paragraphs of this Article III (with appropriate
modifications) shall be given by the Company 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. The
provisions of this Article III shall be in addition to any other rights to
indemnification, contribution or other remedies which an Indemnified Party may
have pursuant to law, equity, contract or otherwise.

         Section 3.4 Contribution. If the indemnification and reimbursement
obligations provided for in any section of this Article III is unavailable or
insufficient to hold harmless the Indemnified Parties in respect of any Damages
referred to herein, then the Indemnifying Party, in lieu of indemnifying such
Indemnified Party, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such Damages as between the Company on the one
hand and the Investor on the other, in such proportion as is appropriate to
reflect the relative fault of the Company and of the Investor in connection with
such statements or omissions, as well as other equitable

                                       10

<PAGE>

considerations. The relative fault of the Company on the one hand and of the
Investor on the other 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 such party, and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.

         The Company and the Investor agree that it would not be just and
equitable if contribution pursuant to this Section 3.4 were determined by pro
rata allocation or by any other method of allocation that does not take account
of the equitable considerations referred to in the immediately preceding
paragraph. The amount paid or payable by an Indemnified Party as a result of the
Damages referred to in the immediately preceding paragraph shall be deemed to
include, subject to the limitations set forth above, any legal or other expenses
reasonably incurred by such Indemnified Party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
Section 3.4, the Investor shall in no event be required to contribute any amount
in excess of the amount by which the total price at which the Registrable
Securities of the Investor were sold to the public (less underwriting discounts
and commissions) exceeds the amount of any damages which the Investor has
otherwise been required to pay by reason of such untrue or alleged untrue
statement or omission or alleged omission. 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.

                                   ARTICLE IV
                                  MISCELLANEOUS

         Section 4.1 No Outstanding Registration Rights. Except as disclosed in
the SEC Documents or under this Agreement, the Company represents and warrants
to the Investor that there is not in effect on the date hereof any agreement by
the Company pursuant to which any holders of securities of the Company have a
right to cause the Company to register or qualify such securities under the
Securities Act or any securities or blue sky laws of any jurisdiction.

         Section 4.2 Term. The obligations of the Company and the rights
provided to the holders of Registrable Securities hereunder shall terminate at
such time as all Registrable Securities have been issued and have ceased to be
Registrable Securities. Notwithstanding the foregoing, Section 1.1(c) and (d),
Article III, Section 4.8, and Section 4.9 shall survive the termination or
expiration of this Agreement until the end of the relevant statutory
limitations.

         Section 4.3 Rule 144. The Company will use its commercially reasonable
efforts to file in a timely manner information, documents and reports in
compliance with the Securities Act and the Exchange Act and will, at its
expense, promptly take such further action as holders of Registrable Securities
may reasonably request to enable such holders of Registrable Securities to sell
Registrable Securities without registration under the Securities Act within the
limitation of the exemptions provided by (a) Rule 144, as such Rule may be
amended from time to time, or (b) any similar rule or regulation hereafter
adopted by the Commission. If at any time the Company is not required to file
such reports, it will, at its expense, forthwith upon the written request of any
holder of Registrable Securities, make available adequate current public
information with respect to the Company within the meaning of paragraph (c)(2)
of Rule 144 or such other information as necessary to permit sales pursuant to
Rule 144. Upon the request of the Investor, the Company will deliver to the
Investor a written statement, signed by the Company's principal executive or
financial officer, as to whether it has complied with such requirements.

                                       11

<PAGE>

         Section 4.4 Certificate. The Company will, at its expense, forthwith
upon the request of any holder of Registrable Securities, deliver to such holder
a certificate, signed by the Company's principal financial officer, stating (a)
the Company's name, address and telephone number (including area code), (b) the
Company's Internal Revenue Service identification number, (c) the Company's
Commission file number, (d) the number of shares of each class of capital stock
outstanding as shown by the most recent report or statement published by the
Company, and (e) whether the Company has filed the reports required to be filed
under the Exchange Act for a period of at least ninety (90) days prior to the
date of such certificate and in addition has filed the most recent annual report
required to be filed there under.

         Section 4.5 Amendment and Modification. No provision of this Agreement
may be waived, unless such waiver is set forth in a writing executed by both
parties to this Agreement. The provisions of this Agreement, including the
provisions of this sentence, may not be amended, modified or supplemented, and
waivers or consents to departures from the provisions hereof may not be given,
unless the Company has obtained the written consent of the holders of a majority
of the then outstanding Registrable Securities. Notwithstanding the foregoing,
the waiver of any provision hereof with respect to a matter that relates
exclusively to the rights of holders of Registrable Securities whose securities
are being sold pursuant to a Registration Statement and does not directly or
indirectly affect the rights of other holders of Registrable Securities may be
given by holders of at least a majority of the Registrable Securities being sold
by such holders; provided that the provisions of this sentence may not be
amended, modified or supplemented except in accordance with the provisions of
the immediately preceding sentence. No course of dealing between or among any
Person having any interest in this Agreement will be deemed effective to modify,
amend or discharge any part of this Agreement or any rights or obligations of
any person under or by reason of this Agreement.

         Section 4.6 Successors and Assigns; Entire Agreement. This Agreement
and all of the provisions hereof shall be binding upon and inure to the benefit
of the parties hereto and their respective successors and permitted assigns. The
Investor may assign its rights under this Agreement to any subsequent holder of
the Registrable Securities, provided that the Company shall have the right to
require any holder of Registrable Securities to execute a counterpart of this
Agreement as a condition to such holder's claim to any rights hereunder. This
Agreement, together with the Securities Purchase Agreement, sets forth the
entire agreement and understanding between the parties as to the subject matter
hereof and merges and supersedes all prior discussions, agreements and
understandings of any and every nature among them.

         Section 4.7 Severability. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that such severability shall be
ineffective if it materially changes the economic benefit of this Agreement to
any party.
