FIRST DEFIANCE FINANCIAL CORP. EMPLOYEE INVESTMENT PLAN

                           Effective September 1, 2000

PURPOSE

     The purpose of the First Defiance Financial Corp.  Employee Investment Plan
(the  "Plan") is to make  available  to  eligible  employees  of First  Defiance
Financial Corp. (the  "Corporation")  and its subsidiaries  (the Corporation and
each  such  subsidiary  company  are  hereinafter  referred  to  as  "Employer")
(employees of the Corporation  and each such subsidiary  company are hereinafter
sometimes referred to as the "Employees") a means of purchasing common shares of
the Corporation at market prices current at the time of purchase through regular
payroll  deductions.  As an added  incentive,  the Employer  will  contribute an
amount  equal  to 15% of each of the  participating  Employee's  actual  payroll
deductions up to $150 per month in accordance  with the terms and conditions set
forth below. See "Enrollment in Plan" and "Contributions by Employer."

     Participation in the Plan is entirely voluntary,  and the Corporation makes
no  recommendations  to  Employees  as to  whether  they  should or  should  not
participate.

ELIGIBILITY

     All permanent  full-time and permanent  part-time Employees of the Employer
who have  attained  the age of 18 and have been  employed by the Employer for at
least six months are  eligible  to  participate  in the Plan at their  election.
Notwithstanding the foregoing, if any Employee otherwise eligible to participate
in the Plan is employed in any state of the United  States where it is not legal
for the Employer to make deductions from his or her pay as hereinafter provided,
such Employee shall not be eligible to participate.

ENROLLMENT IN THE PLAN

     An eligible Employee,  at his/her election,  may enroll as a participant by
(i) filling in and signing a form of payroll  deduction  authorization  and (ii)
filling in and signing an  enrollment  form for the  purchase for the account of
such Employee of common  shares of the  Corporation.  Appropriate  forms for the
foregoing  purposes may be obtained from the human resources  department at each
subsidiary and the  Corporation.  Enrollment  shall become  effective as soon as
practicable  after the  authorization  for payroll  deduction and the enrollment
form are received by the Corporation.

     Enrollment in the Plan by an eligible  Employee will  terminate upon any of
the  following:  (i) the  filing  of a notice  of  termination  or  revision  of
enrollment  by  such  Employee,   (ii)  termination  of  employment,   or  (iii)
termination  of the Plan by the  Corporation  (see  "Amendment  or  Termination"
below).

<PAGE>

CONTRIBUTIONS BY EMPLOYER

     The  Employer  will  contribute  an amount  equal to 15% of the  authorized
payroll deductions of an eligible participating Employee,  subject to a limit of
$150 per month,  toward the purchase of common shares of the Corporation  during
the period such Employee is enrolled in the Plan.

OPERATION OF THE PLAN

     The  Corporation  has  designated  Registrar and Transfer  Company with its
principal  office located at 10 Commerce Drive,  Cranford,  New Jersey 07016, as
Plan Manager (the "Plan Manager") to open and maintain  accounts in the names of
participating   Employees  and  to  make  purchases  of  common  shares  of  the
Corporation on the open market through brokers for the accounts of participating
Employees.  Nothing herein shall restrict the substitution by the Corporation in
its  discretion  of a firm other than  Registrar  and  Transfer  Company as Plan
Manager  under the Plan,  or the right of  Registrar  and  Transfer  Company  to
terminate its services as Plan Manager.

     The Corporation shall pay (i) the Plan Manager's administrative charges for
opening and  maintaining  such accounts;  (ii) the commissions on purchases made
from amounts  deducted  from the pay of Employees  who have opened  accounts and
from amounts  contributed  by the Employer and (iii) the  commissions  and other
charges  in  connection  with  the  reinvestment  of  dividends.   The  broker's
commission  and other charges in connection  with sales or purchases not made by
payroll  deductions or by Employer  contributions  will be borne by the Employee
who orders the transactions for his/her account.

     The  Employer  deducts  funds  from each  participating  Employee's  pay as
authorized  and,  once a month,  forwards the total of amounts  deducted for all
participating Employees,  together with the Employer's contribution, to the Plan
Manager  at its  office  at 10  Commerce  Drive,  Cranford,  New  Jersey  07016,
accompanied by a list of participating Employees and the amount allocable to the
account of each  participating  Employees.  Where funds have been deducted for a
participating  Employee  before a form of notice of  termination  or revision is
received by the Corporation,  such funds,  together with the applicable Employer
contributions,  will be  forwarded to the Plan  Manager in  accordance  with the
procedures  specified  hereinabove,  and the notice of  termination  or revision
shall be effective only as to deductions made subsequent to receipt of notice by
the Corporation.

     For  ease of  administration,  all such  funds  are  forwarded  to the Plan
Manager  through and by the  Corporation  which may or may not  advance  payroll
deductions and/or Employer  contributions on behalf of subsidiaries  before such
funds have been transmitted to the Corporation by all subsidiaries. In any case,
the  Corporation  is reimbursed  for any such  advances or payments  directly or
indirectly  under  arrangements   between  it  and  its  subsidiaries  who  have
participants in the Plan.

     When the funds are received from the Corporation, the Plan Manager promptly
purchases  on the open  market as many full shares as the  aggregate  funds will
allow.  The number of shares  purchased  depends  upon the  market  price of the
Corporation's  common shares at the time such purchases are made.  Purchases are
allocated  by the Plan  Manager at the  average  cost  thereof  to the  accounts
established in proportion to the respective  amount

<PAGE>

received for each Employee's  account.  Allocation is made in full shares and in
fractional interests in shares to the ten-thousandths of a share.

PAYROLL DEDUCTIONS

     Payroll deductions remain effective until terminated by a participant.  The
Employee  specifies  therein the amount to be withheld  from  his/her pay with a
minimum of $50 per month and a maximum of $5,000  per month,  and the  deduction
amount must be in even dollar amounts.  However,  as stated in the section above
entitled  "Contributions  by  Employer,"  the maximum  amount the Employer  will
contribute is $150 per month.

     The  payroll  deduction  may be  revised or  terminated  at any time by the
Employee's  written  request  to the  Corporation  through  the human  resources
department of the respective subsidiary or the Corporation.

PARTICIPANT'S ACCOUNT WITH THE PLAN MANAGER

     At the time of purchase of shares by the Plan Manager pursuant to the Plan,
each Employee for whose account  funds were received  immediately  acquires full
ownership of all shares and may sell,  assign,  hypothecate,  or otherwise  deal
with such  shares in the same  manner  as any  other  shares of the  Corporation
he/she may own.  Unless  otherwise  requested  by the  Employee,  all shares are
registered in the name of the Plan Manager (or the Plan  Manager's  nominee) and
remain so registered until delivery is requested.  The Employee may request that
a  certificate  for any or all of his/her full shares be delivered to him/her at
any time  subject  to such fees as may be  imposed  by the Plan  Manager.  As of
August 1, 2000, that fee was $20.00 per certificate.

     An Employee  who has an account may add other  shares of the  Corporation's
common shares to his/her account at any time by separate purchases arranged with
the Plan Manager or by  delivering  other  shares owned by such  Employee to the
Plan Manager. When any such purchases are made, the Employee is charged with the
commissions.

     The  Employee's  account is credited with all dividends  paid in respect to
the full shares and any fractional  interest in shares held in his/her  account.
Cash dividends are reinvested in the Corporation's  common shares as promptly as
practicable following receipt thereof by the Plan Manager. Brokerage commissions
on the reinvestment of dividends are payable by the Employer.

     Stock  dividends  and/or any stock  splits in respect of shares held in the
Employee's  account are credited to the account without charge.  Distribution of
other  securities  and rights to subscribe are sold and the proceeds are handled
in the same manner as a cash dividend.

     The  Employee  may instruct the Plan Manager at any time to sell any or all
of his/her  full  shares and the  fractional  interest in shares held in his/her
account. Upon such sale, the Plan Manager will mail the employee a check for the
proceeds less the brokerage commission and any transfer taxes,  registration fee
or other normal charges which are payable by the Employee.

<PAGE>

     Each  Employee  receives  a  periodic   statement  from  the  Plan  Manager
describing activity in the account during the preceding quarter.

     The  Corporation  will deliver or will cause the Plan Manager to deliver to
each Employee as promptly as practicable,  by mail or otherwise,  all notices of
meetings, proxy statements, and other material distributed by the Corporation to
its stockholders.  The full shares of stock in each Employee's account are voted
in accordance with the Employee's  signed proxy  instructions  duly delivered to
the Plan Manager.  There is no charge to the  Employees  for the Plan  Manager's
retention  or delivery of stock  certificates  or in  connection  with  notices,
proxies, or other such material.

CLOSING PARTICIPANT'S ACCOUNT

     An Employee who terminates his payroll deduction  authorization may request
the Plan Manager to maintain or close  his/her  account.  He/She may direct that
all full shares and any fractional interest in shares in his/her account be sold
and the net proceeds  remitted to him/her or may request that the full shares in
the account be  delivered  to him/her  along with a check  representing  the net
proceeds of the sale of the fractional interest in the shares.

AMENDMENT OR TERMINATION

     The  Corporation  reserves the right to discontinue  the use of its payroll
deduction  facilities  for  this  purpose  at any time  such  action  is  deemed
advisable  in its  judgment,  and it also has the  right to amend,  suspend,  or
discontinue  the Plan at any time. Any such  amendment or  termination  will not
result  in  the  forfeiture  of  any  funds  deducted  from  the  salary  of any
participant or contribution by the Employer on behalf of any participant,  or of
any shares or fractional interest in shares purchased for the participant or any
dividends or other  distribution in respect of such shares  effective before the
effective  date of amendment or termination of the Plan. The Plan is not subject
to the provisions of the Employer Retirement Income Security Act of 1974.

FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATION IN THE PLAN

     The Employer's  contribution  is treated as "earned income" to the Employee
under present U.S. tax law, and the Employer withholds federal income taxes (and
state and local taxes,  where  applicable) upon the basis of each  participating
Employee's  actual  salary  plus the  Employer's  contribution  under  the Plan.
Commissions  paid by the  Employer  are also  treated as "earned  income" to the
participating  Employee. The Plan is not qualified pursuant to Section 401(a) of
the Internal Revenue Code. Dividends on all shares purchased under the Plan also
are subject to income taxes, but such taxes are not withheld by the Corporation.
Dividends  will be reported on the  Employee's  Form  1O99-DIV.  For purposes of
determining  taxable gain or loss on sales of shares  purchased  under the Plan,
the cost of such shares is the  purchase  price of such  shares,  including  the
portion of the purchase price contributed by the Employer.

     There is no guarantee  under the Plan against loss because of  fluctuations
in the market  price of the common  shares of the  Corporation.  In seeking  the
benefits of share ownership, each investor also must accept the risks.

RESTRICTIONS ON RESALE

     This  Prospectus  is not  available  for  the  resale  of  shares  acquired
hereunder by persons who may be deemed to be "affiliates"  within the definition
thereof set forth in Rule 405 of the Securities and Exchange Commission ("SEC").
Rule 405, in effect, defines "affiliates" as persons who "directly or indirectly
through one or more  intermediaries  controls,  or is controlled by, or is under
common control with" the Corporation.  Ordinarily,  this concept only extends to
persons who are executive officers,  directors, or substantial  stockholders (5%
or more) of a corporation.

     Nonaffiliates   may  freely  resell  to  the  public  any  shares  acquired
hereunder.   Affiliates,  however,  may  only  resell  pursuant  to  a  separate
registration statement and prospectus (which the Corporation has no intention of
filing) or, assuming the  availability  thereof,  pursuant to SEC Rule 144. Rule
144 contains a number of conditions to its use including a requirement  that the
Corporation  has filed all reports  required by the  Securities  Exchange Act of
1934, a limitation on the number of shares which may be sold in any given period
of time, and a requirement  that a form (Form 144) be filed at the time an order
to sell is placed. In addition,  executive officers of the Corporation must file
a Form 4 (or Form 5 at the end of the year)  with the  Securities  and  Exchange
Commission and Nasdaq when sales of the Corporation's common shares are made.

into similar agreements; provided, further, that this restriction on
transferability shall apply only to the Initial Offering.

                                      4.
<PAGE>

     In order to enforce the foregoing covenant, the Company may impose stop-
transfer instructions with respect to the Registrable Securities of each
Investor (and the shares or securities of every other person subject to the
foregoing restriction) until the end of such one hundred eighty (180) day
period.

3.   Registration.

     3.1  Demand Registration.

          (a)  Subject to the conditions of this Section 3.1, if the Company
shall receive a written request from the Holders of at least a majority of the
Registrable Securities then outstanding on an as-converted basis (the
"Initiating Holders") that the Company file a registration statement under the
Securities Act covering the registration of Registrable Securities having an
aggregate offering price to the public of at least $15,000,000 and constituting
at least twenty percent (20%) of the outstanding shares of the Company's Common
Stock on an as-converted basis, then the Company shall, within twenty (20) days
of the receipt thereof, give written notice of such request to all Holders, and
subject to the limitations of this Section 3.1, use its best efforts to effect,
as soon as practicable, the registration under the Securities Act of all
Registrable Securities that the Holders request to be registered.

          (b)  Any registration pursuant to this Section 3.1 shall be effected
by means of a firm underwriting and the Company shall include such information
in the written notice referred to in Section 3.1(a). The right of any Holder to
include its Registrable Securities in such registration shall be conditioned
upon such Holder's participation in such underwriting and the inclusion of such
Holder's Registrable Securities in the underwriting to the extent provided
herein. All Holders proposing to distribute their securities through such
underwriting shall enter into an underwriting agreement in customary form with
the underwriter or underwriters selected for such underwriting by a majority in
interest of the Initiating Holders (which underwriter or underwriters shall be
of nationally recognized standing and shall be reasonably acceptable to the
Company). Notwithstanding any other provision of this Section 3.1, if the
underwriter advises the Company that marketing factors require a limitation of
the number of securities to be underwritten (including Registrable Securities),
then the Company shall so advise all Holders of Registrable Securities which
would otherwise be underwritten pursuant hereto, and the number of shares that
may be included in the underwriting shall be allocated to the Holders of such
Registrable Securities on a pro rata basis based on the number of Registrable
Securities held by all such Holders (including Initiating Holders). Any
Registrable Securities excluded or withdrawn from such underwriting shall be
withdrawn from the registration.

          (c)  The Company shall not be required to effect a registration
pursuant to this Section 3.1:

               (i)  prior to the later of (A) the period starting with the date
of filing of, and ending on the date ninety (90) days following the closing of
the Company's Initial Offering and (B) December 11, 2000; or

               (ii) after the Company has filed one (1) registration statement
pursuant to this Section 3.1, and either: (A) such registration has been
declared or ordered effective; or

                                      5.
<PAGE>

(B) the request for such registration has been subsequently withdrawn by the
Initiating Holders, and the Holders have not paid the registration expenses of
such registration (as set forth in Section 3.4), unless the withdrawal is based
upon material adverse information concerning the Company of which the Initiating
Holders were not aware at the time of such request; or

               (iii)  during the period starting with the date of filing of, and
ending on the date ninety (90) days following the closing of the Company's
Initial Offering; provided, that, the Company makes reasonable good faith
efforts to cause such registration statement to become effective; or

               (iv)   if within thirty (30) days of receipt of a written request
from Initiating Holders pursuant to Section 3.1(a), the Company gives notice to
the Holders of the Company's intention to make a public offering within ninety
(90) days, other than pursuant to a Special Registration Statement; or

               (v)    if the Company shall furnish to Holders requesting a
registration statement pursuant to this Section 3.1, a certificate signed by the
Chairman of the Board stating that in the good faith judgment of the Board of
Directors of the Company, it would be seriously detrimental to the Company and
its stockholders for such registration statement to be effected at such time, in
which event the Company shall have the right to defer such filing for a period
of not more than ninety (90) days after receipt of the request of the Initiating
Holders; provided, that, the right to delay a request under Section 3.1 and/or
Section 3.3 shall be exercised by the Company not more than once in any twelve
(12) month period; or

               (vi)   if the Initiating Holders propose to dispose of shares of
Registrable Securities that may be immediately registered on Form S-3 (or a
successor or similar form) pursuant to a request made pursuant to Section 3.3
below; provided, however, that an underwriter agrees to underwrite the
registration of such Registrable Securities on Form S-3 (or a successor or
similar form).

     3.2  Piggyback Registrations. The Company shall notify all Holders of
Registrable Securities in writing at least thirty (30) days prior to the filing
of any registration statement under the Securities Act for purposes of a public
offering of securities of the Company (including, but not limited to,
registration statements relating to secondary offerings of securities of the
Company and to offerings of securities of the Company initiated by any party
exercising its demand registration rights, but excluding registration statements
relating to employee benefit plans and corporate reorganizations or other
transactions under Rule 145 of the Securities Act) and will afford each such
Holder an opportunity to include in such registration statement all or part of
such Registrable Securities held by such Holder. Each Holder desiring to include
in any such registration statement all or any part of the Registrable Securities
held by it shall, within fifteen (15) days after receipt of the above-described
notice from the Company, so notify the Company in writing. Such notice shall
state the intended method of disposition of the Registrable Securities by such
Holder. If a Holder decides not to include all of its Registrable Securities in
any registration statement thereafter filed by the Company, such Holder shall
nevertheless continue to have the right to include any Registrable Securities in
any subsequent registration statement or registration statements as may be filed
by the Company with respect to offerings of its securities, all upon the terms
and conditions set forth herein.

                                      6.
<PAGE>

     If the registration statement under which the Company gives notice under
this Section 3.2 is for an underwritten offering, the Company shall so advise
the Holders of Registrable Securities.  In such event, the right of any such
Holder to be included in a registration pursuant to this Section 3.2 shall be
conditioned upon such Holder's participation in such underwriting and the
inclusion of such Holder's Registrable Securities in the underwriting to the
extent provided herein.  All Holders proposing to distribute their Registrable
Securities through such underwriting shall enter into an underwriting agreement
in customary form with the underwriter or underwriters selected for such
underwriting by the Company.  Notwithstanding any other provision of this
Agreement, if the underwriter determines in good faith that marketing factors
require a limitation of the number of shares to be underwritten, the number of
shares that may be included in the underwriting shall be allocated as follows:
(i) first, to the Company, (ii) second, to the Holders of the Company's Series A
Stock, Series B Stock, Series C Stock and Series D Stock on a pro rata basis
based on the total number of Registrable Securities held by such Holders and
(iii) third, to any stockholder of the Company (other than a Holder) on a pro
rata basis.  No such reduction shall reduce the securities being offered by the
Company for its own account to be included in the registration and underwriting.
In no event will shares of any other selling stockholder be included in such
registration which would reduce the number of shares which may be included by
the Holders, without the written consent of Holders of a majority of the
Registrable Securities proposed to be sold in the offering.  The Company shall
have the right to terminate or withdraw any registration initiated by it under
this Section 3.2 prior to the effectiveness of such registration whether or not
any Holder has elected to include securities in such registration.  The
registration expenses of such withdrawn registration shall be borne by the
Company in accordance with Section 3.4 hereof.  For any Holder which is a
partnership or corporation, the partners, retired partners and stockholders of
such Holder, or the estates and family members of any such partners and retired
partners and any trusts for the benefit of any of the foregoing person shall be
deemed to be a single "Holder", and any pro rata reduction with respect to such
"Holder" shall be based upon the aggregate amount of shares carrying
registration rights owned by all entities and individuals included in such
"Holder," as defined in this sentence.

     3.3  Form S-3 Registration. In case the Company shall receive a written
request from the Holders of at least twenty-five percent (25%) of the
Registrable Securities then outstanding on an as-converted basis that the
Company effect a registration on Form S-3 (or any successor to Form S-3) or any
similar short-form registration statement and any related qualification or
compliance with respect to all or a part of the Registrable Securities owned by
such Holder or Holders, the Company will:

          (a)  promptly give written notice of the proposed registration, and
any related qualification or compliance, to all other Holders of Registrable
Securities; and

          (b)  as soon as practicable, effect such registration and all such
qualifications and compliances as may be so requested and as would permit or
facilitate the sale and distribution of all or such portion of such Holder's or
Holders' Registrable Securities as are specified in such request, together with
all or such portion of the Registrable Securities of any Holder or Holders
joining in such request as are specified in a written request given within
fifteen (15) days after receipt of such written notice from the Company;
provided, however, that

                                      7.
<PAGE>

the Company shall not be obligated to effect any such registration,
qualification or compliance pursuant to this Section 3.3:

               (i)    if Form S-3 (or any successor or similar form) is not
available for such offering by the Holders; or

               (ii)   if the Holders, together with the holders of any other
securities of the Company entitled to inclusion in such registration, propose to
sell Registrable Securities and such other securities (if any) at an aggregate
price to the public of less than $1,000,000; or

               (iii)  if within thirty (30) days of receipt of a written request
from Initiating Holders pursuant to Section 2.2(a), the Company gives notice to
the Holders of the Company's intent to make a public offering within ninety (90)
days, other than pursuant to a Special Registration Statement; or

               (iv)   if the Company shall furnish to the Holders a certificate
signed by the Chairman of the Board of Directors of the Company stating that, in
the good faith judgment of the Board of Directors of the Company, it would be
seriously detrimental to the Company and its stockholders for such Form S-3
registration to be effected at such time, in which event the Company shall have
the right to defer the filing of the Form S-3 registration statement for a
period of not more than ninety (90) days after receipt of the request of the
Holder or Holders under this Section 3.3; provided, that, the right to delay a
request under Section 3.1 and/or Section 3.3 shall be exercised by the Company
not more than once in any twelve (12) month period; or

               (v)    in any particular jurisdiction in which the Company would
be required to qualify to do business or to execute a general consent to service
of process in effecting such registration, qualification or compliance, except
in jurisdictions in which the Company is already qualified to do business or
subject to service of process; or

               (vi)   if the Company has already effected two (2) registrations
on Form S-3 (or any successor or similar form) for the Holders pursuant to this
Section 3.3.

          (c)  Subject to the foregoing, the Company shall file a Form S-3 (or
any successor or similar form) registration statement covering the Registrable
Securities and other securities so requested to be registered as soon as
practicable after receipt of the request or requests of the Holders.

     3.4  Registration Expenses.  The Company shall bear all fees and expenses
incurred in connection with any registration under this Agreement, including
without limitation all registration, filing, qualification, printers' and
accounting fees, fees and disbursements of counsel to the Company, reasonable
fees and disbursements (not to exceed $20,000.00) of a single special counsel
for the Holders for registration under Section 3.1, except that each
participating Holder shall bear its proportionate share of all amounts payable
to underwriters in connection with such offering for discounts and commissions.
The Company shall not, however, be required to pay for expenses of any
registration proceeding begun pursuant to Sections 3.1 or 3.3, the request of
which has been subsequently withdrawn by the Holders, unless the withdrawal is
based upon material adverse information concerning the Company of which the
Holders

                                      8.
<PAGE>

initiating the registration request were not aware at the time of such request.
If the Holders are required to pay their registration expenses, such expenses
shall be borne by the holders of securities (including Registrable Securities)
requesting such registration in proportion to the number of shares for which
registration was requested.

     3.5  Obligations of the Company. Whenever required to effect the
registration of any Registrable Securities, the Company shall, as expeditiously
as reasonably possible:

          (a)  Prepare and file with the SEC a registration statement with
respect to such Registrable Securities and use its best efforts to cause such
registration statement to become effective, and, upon the request of the Holders
of a majority of the Registrable Securities registered thereunder, keep such
registration statement effective until the earlier of the sale of the all of the
Registrable Securities so registered and ninety (90) days subsequent to the
effective date of such registration.

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

          (c)  Furnish to the Holders such number of copies of a prospectus,
including a preliminary prospectus, in conformity with the requirements of the
Securities Act, and such other documents as they may reasonably request in order
to facilitate the disposition of Registrable Securities owned by them.

          (d)  Use its best efforts to register and qualify the securities
covered by such registration statement under such other securities or Blue Sky
laws of such jurisdictions as shall be reasonably requested by the Holders,
provided, that, the Company shall not be required in connection therewith or as
a condition thereto to qualify to do business or to file a general consent to
service of process in any such states or jurisdictions in which the Company is
not already qualified to do business or subject to service of process.

          (e)  In the event of any underwritten public offering, enter into and
perform its obligations under an underwriting agreement, in usual and customary
form, with the managing underwriter(s) of such offering. Each Holder
participating in such underwriting shall also enter into and perform its
obligations under such an agreement.

          (f)  Notify each Holder of Registrable Securities covered by 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 a result of which the prospectus included in such registration statement, as
then in effect, includes an untrue statement of a material fact or omits to
state a material fact required to be stated therein or necessary to make the
statements therein not misleading or incomplete in the light of the
circumstances then existing.

          (g)  Use commercially reasonable efforts to cause such Registrable
Securities to be listed on all exchanges or quotation systems on which the
Company's Common Stock is then listed.

                                      9.
<PAGE>

     3.6  Termination of Registration Rights.  All registration rights granted
under this Section 3 shall terminate and be of no further force and effect five
(5) years after the Company has completed its Initial Offering.  In addition,
the right of any Holder to request inclusion of Registrable Securities in any
registration pursuant to this Section 3 shall terminate if (a) such Holder
(together with its affiliates, partners and former partners) holds less than one
percent (1%) of the Company's outstanding Common Stock (treating all shares of
convertible Preferred Stock on an as-converted basis) and (b) all Registrable
Securities held by and issuable to such Holder (and its affiliates, partners,
former partners, members and former members) may be sold to the public under
Rule 144(k) during any ninety (90) day period.

     3.7  Furnish Information.  It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 3 that
the selling Holders shall furnish to the Company such information regarding
themselves, the Registrable Securities held by them and the intended method of
disposition of such securities as shall be required to effect the registration
of their Registrable Securities.

     3.8  Delay of Registration. No Holder shall have any right to obtain or
seek an injunction restraining or otherwise delaying any such registration as
the result of any controversy that might arise with respect to the
interpretation or implementation of this Section 3.

     3.9  Assignment of Registration Rights.  The rights to cause the Company to
register Registrable Securities pursuant to this Section 3 may be assigned by a
Holder to a transferee or assignee of Registrable Securities which (a) is a
subsidiary, parent, general partner, limited partner, retired partner, member,
retired member, affiliate or trust beneficiaries of a Holder, (b) is a Holder's
family member or trust for the benefit of an individual Holder, (c) is another
RIC with a common investment advisor or (d) acquires at least two hundred fifty
thousand (250,000) shares of Registrable Securities (as adjusted for stock
dividends, stock splits and combinations).  The transferor shall, within ten
(10) days after such transfer, furnish to the Company written notice of the name
and address of such transferee or assignee and the securities with respect to
which such registration rights are being assigned and (B) such transferee shall
agree to be subject to all restrictions set forth in this Agreement.

     3.10 Amendment or Waiver of Registration Rights.  Any provision of this
Section 3 may be amended, and the observance thereof may be waived (either
generally or in a particular instance and either retroactively or
prospectively), only with the written consent of the Company and the Holders of
at least a majority of the Registrable Securities then outstanding, provided
that no Holder of any Registrable Securities shall be bound by any amendment to
or waiver of the terms of any provision of this Section 3 without the express
written consent of such Holder if (i) such amendment or waiver has an adverse
effect on such Holder's rights under this Section 3 and (ii) such amendment or
waiver does not apply to all Holders, or if it does apply to all Holders, the
amendment or waiver adversely affects the rights of such Holder in a manner
which differs from, or to an extent greater than, the effect on any other
Holder.  Subject to the proviso in the preceding sentence, any amendment or
waiver effected in accordance with this Section 3.10 shall be binding upon each
Holder and the Company.  By acceptance of any benefits under this Agreement,
Holders of Registrable Securities hereby agree to be bound by the provisions
hereunder.

                                      10.
<PAGE>

     3.11 Indemnification.  In the event any Registrable Securities are included
in a registration statement under Sections 3.1, 3.2 or 3.3:

          (a)  To the extent permitted by law, the Company will indemnify and
hold harmless each Holder, the partners, officers, directors and legal counsel
of each Holder, any underwriter (as defined in the Securities Act) for such
Holder and each person, if any, who controls such Holder or underwriter within
the meaning of the Securities Act or the Exchange Act, against any losses,
claims, damages, or liabilities (joint or several) to which they may become
subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereof) arise out of or are based upon any of the following statements,
omissions or violations (collectively a "Violation") by the Company: (i) any
untrue statement or alleged untrue statement of a material fact contained in
such registration statement, including any preliminary prospectus or final
prospectus contained therein or any amendments or supplements thereto, (ii) the
omission or alleged omission to state therein a material fact required to be
stated therein, or necessary to make the statements therein not misleading, or
(iii) any violation or alleged violation by the Company or its agents of the
Securities Act, the Exchange Act, any state securities law or any rule or
regulation promulgated under the Securities Act, the Exchange Act or any state
securities law in connection with the offering covered by such registration
statement; and the Company will promptly reimburse each such Holder, partner,
officer or director, underwriter or controlling person for any legal or other
expenses reasonably incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action; provided, however,
that the indemnity agreement contained in this Section 3.11(a) shall not apply
to amounts paid in settlement of any such loss, claim, damage, liability or
action if such settlement is effected without the consent of the Company, which
consent shall not be unreasonably withheld, nor shall the Company be liable in
any such case for any such loss, claim, damage, liability or action to the
extent that it arises out of or is based upon a Violation which occurs in
reliance upon and in conformity with written information furnished expressly for
use in connection with such registration by such Holder, partner, officer,
director, underwriter or controlling person of such Holder.

          (b)  To the extent permitted by law, each Holder will, if Registrable
Securities held by such Holder are included in the securities as to which such
registration qualifications or compliance is being effected, indemnify and hold
harmless the Company, each of its directors, its officers, and legal counsel and
each person, if any, who controls the Company within the meaning of the
Securities Act, any underwriter and any other Holder selling securities under
such registration statement or any of such other Holder's partners, directors or
officers or any person who controls such Holder, against any losses, claims,
damages or liabilities (joint or several) to which the Company or any such
director, officer, controlling person, underwriter or other such Holder, or
partner, director, officer or controlling person of such other Holder may become
subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in
respect thereto) arise out of or are 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 by such Holder under an
instrument duly executed by such Holder and stated to be specifically for use in
connection with such registration; and each such Holder will promptly reimburse
any legal or other expenses reasonably incurred by the Company or any such
director, officer, controlling

                                      11.
<PAGE>

person, underwriter or other Holder, or partner, officer, director or
controlling person of such other Holder in connection with investigating or
defending any such loss, claim, damage, liability or action if it is judicially
determined that there was such a Violation; provided, however, that the
indemnity agreement contained in this Section 3.11(b) shall not apply to amounts
paid in settlement of any such loss, claim, damage, liability or action if such
settlement is effected without the consent of the Holder, which consent shall
not be unreasonably withheld; provided further, that in no event shall the
aggregate of any Holder's indemnity and contribution under this Section 3.11
exceed the net proceeds from the offering of the Registrable Securities received
by such Holder.

          (c)  Promptly after receipt by an indemnified party under this Section
3.11 of notice of the commencement of any action (including any governmental
action), such indemnified party will, if a claim in respect thereof is to be
made against any indemnifying party under this Section 3.11, 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 party
similarly noticed, to assume the defense thereof with counsel reasonably
satisfactory to the indemnified party; provided, however, that an indemnified
party shall have the right to retain its own counsel, with the fees and expenses
to be paid by the indemnifying party, if representation of such indemnified
party by the counsel retained by the indemnifying party would be inappropriate
due to actual or reasonably likely differing interests between such indemnified
party and any other party represented by such counsel in such proceeding. The
failure to deliver written notice to the indemnifying party within a reasonable
time of the commencement of any such action, if materially prejudicial to its
ability to defend such action, shall relieve such indemnifying party of any
liability to the indemnified party to the extent of such material prejudice
under this Section 3.11, but the omission to so deliver written notice to the
indemnifying party will not relieve it of any liability that it may have to any
indemnified party otherwise than under this Section 3.11.

          (d)  If the indemnification provided for in this Section 3.11 is held
by a court of competent jurisdiction to be unavailable to an indemnified party
with respect to any losses, claims, damages or liabilities referred to herein,
the indemnifying party, in lieu of indemnifying such indemnified party
thereunder, shall to the extent permitted by applicable law contribute to the
amount paid or payable by such indemnified party as a result of such loss,
claim, damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnifying party on the one hand and of the indemnified
party on the other in connection with the Violation(s) that resulted in such
loss, claim, damage or liability, as well as any other relevant equitable
considerations. The relative fault of the indemnifying party and of the
indemnified party shall be determined by a court of law by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission to state a material fact relates to information supplied by the
indemnifying party or by the indemnified party and the parties' relative intent,
knowledge, access to information and opportunity to correct or prevent such
statement or omission; provided, that, in no event shall the aggregate indemnity
and contribution obligations by a Holder hereunder exceed the net proceeds from
the offering of the Registrable Securities received by such Holder.

          (e)  The obligations of the Company and Holders under this Section
3.11 shall survive completion of any offering of Registrable Securities in a
registration statement. No

                                      12.
<PAGE>

indemnifying party, in the defense of any such claim or litigation, shall,
except with the consent of each indemnified party, consent to entry of any
judgment or enter into any settlement 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.

     3.12 Rule 144 Reporting. With a view to making available to the Holders the
benefits of certain rules and regulations of the SEC which may permit the sale
of the Registrable Securities to the public without registration or pursuant to
a registration on Form S-3 (or its successor), the Company agrees to use its
best efforts to:

          (a)  Make and keep public information available, as those terms are
understood and defined in SEC Rule 144 or any similar or analogous rule
promulgated under the Securities Act, at all times after the effective date of
the first registration filed by the Company for an offering of its securities to
the general public.

          (b)  File with the SEC, in a timely manner, all reports and other
documents required of the Company under the Exchange Act;

          (c)  So long as a Holder owns any Registrable Securities, furnish to
such Holder forthwith upon request: a written statement by the Company as to its
compliance with the reporting requirements of said Rule 144 of the Securities
Act, and of 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 as a Holder may reasonably
request in availing itself of any rule or regulation of the SEC allowing it to
sell any such securities without registration.

4.   Covenants of the Company.

     4.1  Basic Financial Information and Reporting.

          (a)  The Company will maintain true books and records of account in
which full and correct entries will be made of all its business transactions
pursuant to a system of accounting established and administered in accordance
with generally accepted accounting principles consistently applied, and will set
aside on its books all such proper accruals and reserves as shall be required
under generally accepted accounting principles consistently applied.

          (b)  The Company shall deliver to each Investor (with its affiliates)
which owns at least two hundred fifty thousand (250,000) shares of Registrable
Securities (as adjusted for stock dividends, stock splits, recapitalizations and
the like) (a "Major Investor"),

               (i)  as soon as practicable, but in any event within ninety (90)
days after the end of each fiscal year of the Company, an income statement for
such fiscal year, with comparisons to the Company's annual budget, a balance
sheet of the Company as of the end of such fiscal year, with comparisons to the
Company's annual budget, and a statement of cash flows of the Company for such
fiscal year, with comparisons to the Company's annual budget, such year-end
financial reports to be in reasonable detail, prepared in accordance with

to discuss the affairs, finances and accounts of the Company or any of its
subsidiaries with its officers, to examine the books of accounts and records and
to review such information as is reasonably requested; provided, however, that
the Company shall not be obligated under this Section 4.2 with respect to a
competitor of the Company or with respect to information which the Board of
Directors determines in good faith is confidential and should not, therefore, be
disclosed.

     4.3  Confidentiality of Records. Each Investor agrees to use, and to use
its best efforts to insure that its authorized representatives uses, the same
degree of care as such Investor uses to protect its own confidential information
to keep confidential any information furnished to it which the Company
identifies as being confidential or proprietary (so long as such information is
not in the public domain), except that such Investor may disclose such
proprietary or confidential information to any partner, subsidiary, affiliate,
investment advisor or parent (or any of their respective professional advisors,
including, but not limited to, accountants, attorneys and tax and investment
advisors) of such Investor for the purpose of evaluating its investment in the
Company as long as such partner, subsidiary, affiliate, investment advisor or

limited to, accountants, attorneys and tax and investment advisors) is advised
of the confidentiality provisions of this Section 4.3.

     4.4  Reservation of Common Stock. The Company will at all times reserve and

reporting requirements of the Exchange Act, the Company shall timely file all
required reports pursuant to the Exchange Act. Additionally, the Company shall
make available to Investors the information contemplated by Rule 144A. At such
time that any stock held by an Investor is eligible for transfer pursuant to

restrictive legend from the applicable stock certificate at no cost to such
Investor.

     4.7  Termination of Covenants.  All covenants of the Company contained in
Section 4 of this Agreement (other than Section 4.5) shall expire and terminate
as to each Investor on the effective date of the registration statement
pertaining to the Initial Offering.

5.   Preemptive Rights.

     5.1  Subsequent Offerings. Each Major Investor shall have a preemptive
right to purchase up to its pro rata share of all Equity Securities that the
Company may, from time to time, propose to sell and issue after the date of this
Agreement, other than the Equity Securities excluded by Section 5.6 hereof. Each
Investor's pro rata share is equal to the ratio of (A) the number of shares of
the Company's Common Stock (including all shares of Common Stock issued or
issuable upon conversion of the Shares) which such Investor is deemed to be a
holder immediately prior to the issuance of such Equity Securities to (B) the
total number of shares of the Company's outstanding Common Stock on a fully-
diluted basis (including all shares of Common Stock issued or issuable upon the
exercise of outstanding options, warrants or convertible securities) immediately
prior to the issuance of the Equity Securities.

     5.2  Exercise of Rights. If the Company proposes to issue any Equity
Securities, it shall give each Investor written notice of its intention,
describing the Equity Securities, the price and the terms and conditions upon
which the Company proposes to issue the same. Each Investor shall have fifteen
(15) days from the receipt of such notice to agree to purchase up to its pro
rata share of the Equity Securities for the price and upon the terms and
conditions specified in the notice by giving written notice to the Company and
stating therein the quantity of Equity Securities to be purchased.
Notwithstanding the foregoing, the Company shall not be required to offer or
sell such Equity Securities to any Investor who would cause the Company to be in
violation of applicable federal securities laws by virtue of such offer or sale.

     5.3  Issuance of Equity Securities to Other Investors. If not all of the
Investors elect to purchase their pro rata share of the Equity Securities, then
the Company shall promptly notify in writing the Investors who do so elect and
shall offer such Investors the right to acquire such unsubscribed shares. The
Investors shall have five (5) business days after receipt of such notice to
notify the Company of its election to purchase all or a portion thereof of the
unsubscribed shares. If the Investors fail to exercise in full their preemptive
rights, the Company shall have ninety (90) days thereafter to sell the Equity
Securities in respect of which the Investor's rights were not exercised, at a
price and upon general terms and conditions materially no more favorable to the
purchasers thereof than specified in the Company's notice to the Investors
pursuant to Section 5.2 hereof. If the Company has not sold such Equity
Securities within ninety (90) days of the notice provided pursuant to Section
5.2, the Company shall not thereafter issue or sell any Equity Securities,
without first offering such securities to the Investors in the manner provided
above.

     5.4  Termination of Preemptive Rights. The preemptive rights established by
this Section 5 shall not apply to, and shall terminate upon, the effective date
of the registration statement pertaining to the Initial Offering.

                                      15.
<PAGE>

     5.5  Transfer of Preemptive Rights. The preemptive rights of each Investor
under this Section 5 may be transferred to the same parties, subject to the same
restrictions, as any transfer of registration rights pursuant to Section 3.9.

     5.6  Excluded Securities. The preemptive rights established by this Section
5 shall have no application to any of the following Equity Securities:

          (a)  shares of Common Stock (and/or options, warrants or other Common
Stock purchase rights issued pursuant to such options, warrants or other rights)
(as adjusted for stock splits, recapitalizations and the like) issued or to be
issued to employees, officers or directors of, or consultants or advisors to the
Company or any subsidiary, pursuant to stock purchase or stock option plans or
other arrangements that are approved by the Board of Directors;

          (b)  stock issued pursuant to any rights or agreements outstanding as
of the date of this Agreement, options, warrants and convertible promissory
notes outstanding as of the date of this Agreement; and stock issued pursuant to
any such rights or agreements granted after the date of this Agreement,
provided, that, the preemptive rights established by this Section 5 applied with
respect to the initial sale or grant by the Company of such rights or
agreements;

          (c)  any Equity Securities issued for consideration other than cash
pursuant to a merger, consolidation, acquisition or similar business combination
in which the stockholders of the Company immediately prior to such transaction
own less than 50% of the voting power of the surviving entity;

          (d)  shares of Common Stock issued in connection with any stock split,
stock dividend or recapitalization by the Company;

          (e)  shares of Common Stock issued upon conversion of the Shares;

          (f)  any Equity Securities that are issued by the Company pursuant to
a registration statement filed under the Securities Act; and

          (g)  any Equity Securities issued pursuant to any commercial loan or
leasing transaction approved by the Board of Directors.
