                         AND WARRANT PURCHASE AGREEMENT

THIS SERIES B CONVERTIBLE PREFERRED STOCK AND WARRANT PURCHASE AGREEMENT (this
"Agreement") is made and entered into effective as of March 4, 2004, by and
among TRANS-INDUSTRIES, INC., a Delaware corporation (the "Company"), and the
purchaser or purchasers listed on Annex I attached hereto (each, a "Purchaser,"
and collectively, the "Purchasers").

WHEREAS, the Company desires to issue and sell to the Purchasers, and the
Purchasers desire to purchase from the Company, (i) newly issued shares of the
Company's Series B Convertible Preferred Stock, par value $1.00 per share (the
"Series B Convertible Preferred Stock"), the powers, preferences and relative,
participating and other special rights and the qualifications, limitations and
restrictions of which are set forth in the Certificate of Designation (as
defined below), a copy of which is attached to this Agreement as Exhibit A, and
(ii) the Company's warrants to purchase shares of Common Stock, par value $0.10
per share (the "Common Stock"), of the Company in the form attached to this
Agreement as Exhibit B (the "Warrants"), at the price per share and upon and
subject to the other terms and conditions set forth in this Agreement;
ACCORDINGLY, the Company and the Purchasers hereby agree as follows:
AUTHORIZATION OF SALE OF THE SERIES B PREFERRED STOCK AND WARRANTS

      The Company has authorized the issuance and sale to the Purchasers of (a)
up to 193,798.45 shares of Series B Convertible Preferred Stock and (b) Warrants
to purchase in the aggregate up to 145,348.84 shares of Common Stock, all upon
and subject to the terms and conditions set forth in this Agreement.

AGREEMENT TO SELL AND PURCHASE THE SERIES B PREFERRED STOCK AND WARRANTS

            PURCHASE AND SALE

      Upon the terms and subject to the terms and conditions set forth in this
Agreement, at the Closing (as defined below), the Company shall issue and sell
to each Purchaser, and each Purchaser shall purchase from the Company, (a) that
number of shares of Series B Convertible Preferred Stock which is set forth
opposite such Purchaser's name on Annex I hereto, and (b) a Warrant or Warrants
to purchase in the aggregate up to that number of shares of Common Stock which
is set forth opposite such Purchaser's name on Annex I hereto. The shares of
Series B Convertible Preferred Stock and the Warrants to be issued and sold by
the Company to the Purchasers hereunder are referred to herein collectively as
the "Purchased Shares" and the "Purchased Warrants," respectively.

            PURCHASE PRICE

      The total purchase price payable to the Company by each Purchaser for all
of the Purchased Shares and Purchased Warrants to be issued and sold to such
Purchaser hereunder shall be an amount equal to $7.74 multiplied by the number
of Purchased Shares set forth

<PAGE>

opposite such Purchaser's name on Annex I hereto. The aggregate purchase price
payable to the Company for all of the Purchased Shares and Purchased Warrants to
be issued and sold by the Company hereunder (collectively, the "Purchased
Securities") shall be $1,500,000 (the "Purchase Price"). Such purchase price
shall be deemed to include the consideration payable to the Company for both
such Purchased Shares and such Purchased Warrants, to be allocated $1,498,546.51
to the Purchased Shares and $1,453.49 to the Purchased Warrants.

            USE OF PROCEEDS

      The Company shall use the proceeds of the sale of the Purchased Shares to
pay the fees and expenses incurred by the Company in connection with the
transactions contemplated by this Agreement and for working-capital and other
general corporate purposes, including the payment of accounts payable,
delinquent taxes and indebtedness to banks (including up to $250,000 to Comerica
Bank).

            OPTION TO PURCHASE SERIES B-1 CONVERTIBLE PREFERRED STOCK AND
            WARRANTS

      (a) Effective as of the Closing, and subject to the approval of the
shareholders of the Company as may be required under certain National
Association of Securities Dealers, Inc. ("NASD") rules providing for qualitative
listing requirements applicable to securities traded on the Nasdaq National
Market and Nasdaq SmallCap Market and any other approval, authorization or
waiver that may be required by any state or other institution, persons or
agencies, including without limitation, the Securities and Exchange Commission
("SEC") ("Shareholder Approval"), and subject to the refinancing of the
Company's bank debt on terms reasonably satisfactory to Purchasers (which
condition Purchasers may waive), the Purchasers are hereby granted the option
(the "Option") by the Company to purchase shares of Series B-1 Convertible
Preferred Stock and additional Warrants to purchase shares of Common Stock at a
price of $3.00 per share. The Purchasers shall have no obligation to exercise
the Option. The total purchase price for the shares of Series B-1 Convertible
Preferred Stock and Warrants purchased pursuant to the Option, may, at the sole
discretion of the Purchasers, be between $500,000 and $1,500,000 (the "Option
Purchase Price"). The number of shares of Series B-1 Convertible Preferred Stock
to be issued to the Purchaser upon the exercise of the Option shall be a number
equal to the Option Purchase Price divided by $9.00 (the "Option Purchase Price
Per Share" which shall be subject to adjustment as set forth in Section
2.4(d)-(f)). The Warrants to be purchased upon the exercise of the Option shall
entitle the Purchasers to purchase that number of shares of Common Stock equal
to the product of (x) 25% and (y) the number of shares of Common Stock initially
issuable upon conversion of the shares of Series B-1 Convertible Preferred Stock
purchased upon the exercise of the Option. For example, if 100,000 shares of
Series B-1 Convertible Preferred Stock are purchased upon the exercise of the
Option, and assuming that each such share is initially convertible into three
(3) shares of Common Stock, then the Warrants would entitle the Purchasers to
purchase 75,000 shares of Common Stock (100,000 x 3 x 25% = 75,000).

      (b) The Option may be exercised by the Purchasers by providing written
notice to the Company at any time after the Company obtains Shareholder Approval
but prior to 5:00 p.m. EST on January 3, 2005. Purchaser's written notice to the
Company shall specify the Option Purchase Price.

      (c) Within thirty (30) days after Purchaser's written notice is delivered
to the Company, the Company and the Purchaser shall enter into agreements on
substantially similar

<PAGE>

terms to those contained in this Agreement and the Transaction Documents
pursuant to which the Purchasers shall purchase and the Company shall issue the
shares of Series B-1 Convertible Preferred Stock and the Warrants. The terms of
the Series B-1 Convertible Preferred Stock shall be identical to the terms of
the Series B Convertible Preferred Stock, except that the purchase price per
share of the Series B-1 Convertible Preferred Stock shall be $9.00, the dividend
rate shall be $.45 per share and the liquidation preference shall be $9.00 per
share. In addition, the Series B-1 Convertible Preferred Stock and the Series B
Convertible Preferred Stock will share pari passu in any liquidation proceeds
pro rata based on the amount owed.

      (d) If and whenever the Company subsequent to the date hereof:

            (i) declares a dividend upon, or makes any distribution in respect
of, any shares of capital of the Company, payable in Common Stock (other than
upon conversion of the Series B Convertible Preferred Stock or the exercise of
the Warrants), Purchase Rights or Convertible Securities (as used herein:
"Purchase Rights" means any warrants or other rights to subscribe for or to
purchase, or any options for the purchase of, Common Stock; and "Convertible
Securities" means stock or security convertible into or exchangeable for Common
Stock); or

            (ii) subdivides its outstanding Common Stock into a larger number of
Common Stock; or

            (iii) combines its outstanding Common Stock into a smaller number of
Common Stock,

then the Option Purchase Price Per Share shall be adjusted to that price
determined by multiplying the Option Purchase Price Per Share in effect
immediately prior to such event by a fraction, (A) the numerator of which shall
be the total number of outstanding Common Stock immediately prior to such event,
and (B) the denominator of which shall be the total number of outstanding Common
Stock immediately after such event, treating as outstanding all Common Stock
issuable upon conversions or exchanges of any such Convertible Securities issued
in such dividend or distribution and exercises of any such Purchase Rights
issued in such dividend or distribution.

      (e) If any adjustment of the Option Purchase Price Per Share pursuant to
Section 2.4(d) shall result in an adjustment of less than $.0001, no such
adjustment shall be made, but any such lesser adjustment shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any adjustments so carried forward, shall amount
to $.0001; provided that upon any adjustment of the Option Purchase Price Per
Share resulting from (i) the declaration of a dividend upon, or the making of
any distribution in respect of, any shares of capital stock of the Company
payable in Common Stock, Purchase Rights or Convertible Securities or (ii) the
reclassification by subdivision, combination or otherwise, of the Common Stock
into a greater or smaller number of Common Stock, the foregoing figure of $.0001
(or such figure as last adjusted) shall be proportionately adjusted; and
provided, further, that upon the exercise of the Option, the Company shall make
all necessary adjustments (to the nearest .0001 of a cent) not theretofore made
to the Exercise Price up to and including the date upon which the Option is
exercised.

<PAGE>

      (f) If and whenever subsequent to the date hereof the Company shall effect
(i) any reorganization, reclassification or recapitalization of any shares of
capital stock of the Company (other than in the cases referred to in Section
2.4(d)), (ii) any consolidation or merger of the Company with or into another
Person, (iii) the sale, transfer or other disposition of the property, assets or
business of the Company as an entirety or substantially as an entirety or (iv)
any other transaction (or any other event shall occur) as a result of which
holders of Common Stock become entitled to receive any other securities and/or
property (including, without limitation, cash) with respect to or in exchange
for the Common Stock, there shall thereafter be deliverable upon the exercise of
the Option or any portion thereof (in lieu of or in addition to the shares of
Series B-1 Convertible Preferred Stock and Warrants theretofore deliverable, as
appropriate) the number of other securities and/or the amount of property
(including, without limitation, cash) to which the Purchasers would have been
entitled upon such reorganization, reclassification, recapitalization,
conversion, consolidation, merger, sale, transfer, disposition or other
transaction or upon the occurrence of such other event, and at the same
aggregate Option Purchase Price Per Share.

      Prior to and as a condition of the consummation of any transaction or
event described in the preceding sentence, the Company shall make and undertake
lawful, adequate and equitable written adjustments, binding upon the Company
and/or its successor entity, as applicable, in the application of the provisions
set forth herein for the benefit of the Purchasers, so that all such provisions
shall thereafter be applicable, as nearly as possible, in relation to any other
securities or other property thereafter deliverable upon exercise of the Option
and so that the Purchaser will (prior to exercise of the Option ) enjoy all of
the rights and benefits enjoyed by any Person who shall have acquired any other
securities and/or property in connection with any such transaction or event,
including, without limitation, any subsequent tender offer or redemption of any
other securities.

respects with the requirements of the 1934 Act, and none of the Exchange Act
Filings contained any untrue statement of a material fact or omitted to state a
material fact required to be stated therein or necessary to make the statements

            BROKERS AND FINDERS

            Except as set forth in (b) below, no action has been taken by the
                  Company or any other person on the Company's behalf that would
                  give rise to any valid claim against the Company or any

                  relationship. The Company has waived any claim of conflict of
                  interest that might arise by virtue of Relational's
                  representation of the Company and the Purchasers. Relational
                  shall receive a fee from the Company, but not from the

            DISCLOSURE

No representation or warranty made by the Company in this Agreement or in any
other writing furnished pursuant hereto contains an untrue statement of a
material fact or omits to state a material fact necessary to make the statements
and facts contained herein or therein, in light of the circumstances in which
they were or are made, not misleading

REPRESENTATIONS AND WARRANTIES OF THE PURCHASERS

Each Purchaser severally (as to itself only and not with respect to any other
Purchaser) represents and warrants to the Company as follows:

            AUTHORIZATION

Such Purchaser has the requisite power and authority to execute and deliver the
Transaction Documents to which it is a party and to perform its obligations
under such Transaction Documents. The execution and delivery by such Purchaser
of the Transaction Documents to which it is a party and the performance by such
Purchaser of its obligations under such Transaction Documents have been duly
authorized by all necessary action on its part, and no other proceedings on its
part are necessary to authorize its execution and delivery of such Transaction
Documents or its performance of its obligations under such Transaction
Documents.

            DUE EXECUTION AND DELIVERY; BINDING OBLIGATIONS

Each Transaction Document to which such Purchaser is a party has been duly
executed and delivered by such Purchaser, and each such Transaction Document
constitutes the legal, valid and binding obligation of such Purchaser,
enforceable against such Purchaser in accordance with its terms, except as such
enforcement may be limited by bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer or conveyance or similar laws relating to or
limiting creditors' rights generally or by equitable principles relating to
enforceability and except as rights of indemnity or contribution may be limited
by federal or state securities or other laws or the public policy underlying
such laws.

            CONSENTS AND APPROVALS

The execution and delivery by such Purchaser of each Transaction Document to
which it is a party, and the performance by such Purchaser of its obligations
under each such Transaction Document, do not and will not require any consent,
approval, license, permit, order or authorization of, or any registration,
declaration or filing with, any Person (including any governmental agency,
entity or authority), except for (i) such as have been obtained or made and

<PAGE>

are in full force and effect, and (ii) the approval of the shareholders of the
Company which may be required by NASD listing standards.

            INVESTMENT REPRESENTATIONS

Solely for establishing that the offer, sale and issuance of the Purchased
Securities being purchased by such Purchaser pursuant to this Agreement are
exempt from the registration requirements of the Securities Act and the
comparable provisions of state securities laws and not in any way to mitigate
the responsibility or liability of the Company for any breach of the
representations and warranties made by the Company in this Agreement, on which
such Purchaser is relying in full in connection with its, his or her decision to
invest in the Company:

            Such Purchaser is acquiring the Purchased Securities to be purchased
                  by it under this Agreement, for its own account, for
                  investment and not with a view to the distribution thereof in
                  violation of the Securities Act or applicable state securities
                  laws.

            Such Purchaser understands that the Purchased Securities have not
                  been registered under the Securities Act or applicable state
                  securities laws by reason of their issuance by the Company in
                  transactions exempt from the registration requirements of the
                  Securities Act and applicable state securities laws, and that
                  the Company's reliance upon such exemptions is based in part
                  on the representations of the Purchasers contained in this
                  Agreement; and that each such security must be held
                  indefinitely unless a subsequent disposition thereof is
                  registered under the Securities Act and applicable state
                  securities laws or is exempt from registration.

            Such Purchaser further understands that the exemption from
                  registration under the Securities Act afforded by Rule 144
                  (the provisions of which are known to such Purchaser) depends
                  on the satisfaction of various conditions and that, if
                  applicable, Rule 144 affords the basis for sales of only
                  limited amounts and under limited circumstances.

            Such Purchaser has had the opportunity to ask questions of the
                  Company's officers and directors about the business and
                  financial condition of the Company and its subsidiaries,
                  understands that its, his or her purchase of the Purchased
                  Securities being purchased by it pursuant to this Agreement,
                  are speculative investments which involve a high degree of
                  risk of loss of the entire investment therein; and has such
                  knowledge and experience in financial and business matters
                  that it is capable of evaluating the risks and merits of its
                  investment in such Purchased Securities.

            Such Purchaser is an "accredited investor" as such term is defined
                  in Rule 501 of Regulation D promulgated under the Securities
                  Act.

            Such Purchaser has not employed any broker or finder in connection
                  with the transactions contemplated by the Transaction
                  Documents. Relational is acting as an intermediary between the
                  Company and the Purchasers in this transaction, both of whom
                  are aware of such relationship. The Purchasers have waived any
                  claim of conflict of interest that might arise by virtue of
                  Relational's representation of the Company and the Purchasers.
                  Relational

<PAGE>

                  shall receive a fee from the Company, but not from the
                  Purchasers, for the investment contemplated herein.

            The principal office or residence of such Purchaser is located at
                  the address for such Purchaser specified on Annex I hereto,
                  and substantially all of the decisions of such Purchaser with
                  respect to its, his or her investment pursuant to this
                  Agreement were made at such location.

SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS

Notwithstanding any investigation made at any time by or on behalf of any party
to this Agreement, all covenants, agreements, representations and warranties
made by the Company and the Purchasers in this Agreement and in any of the other
Transaction Documents shall survive the execution and delivery of this Agreement
and the issuance and delivery to the Purchasers of the Purchased Securities.

INDEMNIFICATION

            INDEMNIFICATION OF PURCHASER INDEMNITEES

The Company shall indemnify, defend and hold each Purchaser and each of their
respective heirs, beneficiaries, officers, directors, partners, managing
directors, affiliates, employees, agents, consultants, representatives,
successors and assigns (each a "Purchaser Indemnitee") harmless from and against
all Losses (as hereinafter defined) incurred or suffered by a Purchaser
Indemnitee arising out of, relating to or resulting from (i) any breach of any
of the representations or warranties made by the Company in this Agreement or in
any of the other Transaction Documents or (ii) any breach of any of the
covenants or agreements made by the Company in this Agreement or in any of the
other Transaction Documents. Such right of indemnification shall be in addition
to and not in lieu of any and all other rights and remedies available to the
Purchasers at law or in equity.

            INDEMNIFICATION PRINCIPLES

      For purposes of this Agreement, "Losses" shall mean and include each and
all of the following items: claims, actions, demands, losses (including losses
of earnings), liabilities, obligations, payments, damages (actual, punitive and
consequential), charges, judgments, fines, penalties, amount paid in settlement,
costs and expenses (including interest which may be imposed in connection
therewith, costs and expenses of investigation, actions, suits, proceedings,
demands, assessments, and fees, expenses and disbursements of counsel,
consultants and other experts).

TRANSFERS OF SECURITIES

            RESTRICTIVE LEGENDS; EXCHANGES; LOST, STOLEN OR MUTILATED
            CERTIFICATES

Each certificate or other instrument evidencing Purchased Securities and each
certificate or other instrument for any such Purchased Securities issued to
subsequent transferees of any such Purchased Securities shall (unless otherwise
permitted by the provisions of Section 8.3) be stamped or otherwise imprinted
with a legend in substantially the following form:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
      INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933
      OR ANY STATE SECURITIES

<PAGE>
\
      LAWS. THESE SECURITIES MAY NOT BE SOLD OR TRANSFERRED IN THE ABSENCE OF
      SUCH REGISTRATION OR AN EXEMPTION THEREFROM UNDER SAID ACT OR APPLICABLE
      STATE SECURITIES OR BLUE SKY LAWS.

      "ADDITIONALLY, THE TRANSFER OF THESE SECURITIES IS SUBJECT TO CERTAIN
      CONDITIONS SPECIFIED IN THE SERIES B CONVERTIBLE PREFERRED STOCK AND
      WARRANT PURCHASE AGREEMENT DATED AS OF March 4, 2004, AMONG THE ISSUER
      HEREOF AND THE PURCHASERS PARTY THERETO. UPON THE FULFILLMENT OF CERTAIN
      CONDITIONS SPECIFIED THEREIN, THE ISSUER HEREOF HAS AGREED TO DELIVER TO
      THE HOLDER HEREOF A NEW CERTIFICATE, NOT BEARING THESE LEGENDS, FOR THE
      SECURITIES REPRESENTED HEREBY REGISTERED IN THE NAME OF THE HOLDER HEREOF.
      COPIES OF SUCH AGREEMENT MAY BE OBTAINED AT NO COST BY WRITTEN REQUEST
      MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE
      ISSUER HEREOF."

            NOTICE OF TRANSFER

            As used herein, "Restricted Securities" means (a) Purchased Shares,
                  (b) shares of Common Stock issuable upon conversion of the
                  Purchased Shares in accordance with the Certificate of
                  Incorporation, (c) Purchased Warrants, and (d) shares of
                  Common Stock issuable upon exercise of the Purchased Warrants
                  in accordance with the terms thereof. The holder of any
                  Restricted Securities, by acceptance thereof, agrees, prior to
                  any transfer of such Restricted Securities, to give written
                  notice to the Company of such holder's intention to effect
                  such transfer and to comply in all other respects with the
                  provisions of this Section 8.2. Each such notice shall
                  describe the manner and circumstances of the proposed transfer
                  and shall be accompanied, if reasonably requested by the
                  Company, by the written opinion, addressed to the Company, of
                  counsel for the holder of such Restricted Securities, as to
                  whether in the opinion of such counsel (which opinion and
                  counsel shall be reasonably satisfactory to the Company and
                  which counsel may be the in-house counsel of such holder) such
                  proposed transfer involves a transaction requiring
                  registration of such Restricted Securities under the
                  Securities Act; provided, however, that (i) in the case of a
                  holder of Restricted Securities which is a partnership or a
                  limited liability company, no such opinion of counsel shall be
                  necessary for a transfer by such holder of Restricted
                  Securities to a partner or member of such holder of Restricted
                  Securities, or a retired partner or member of such holder who
                  retires after the date hereof, or the estate of any such
                  partner or member or retired partner or member, if in each
                  case the transferee agrees in writing to be subject to the
                  terms of this Section 8 to the same extent as if such
                  transferee were originally a signatory to this Agreement, (ii)
                  in the case of a holder of Restricted Securities which is a
                  corporation or a limited liability company, no such opinion of
                  counsel shall be necessary for a transfer by such holder of
                  Restricted Securities to an affiliate, officer, director,
                  member or manager of such entity, and (iii) no such opinion
                  shall be required in connection with a transfer pursuant to
                  Rule 144, provided,

<PAGE>

                  that the Company, if reasonably requested by it, shall be
                  provided with customary written representations relating to
                  such transaction.

            If in the opinion of such counsel (if such opinion is required
                  hereunder) the proposed transfer of Restricted Securities may
                  be effected without registration under the Securities Act, the
                  holder of such Restricted Securities shall thereupon be
                  entitled to transfer such Restricted Securities in accordance
                  with the terms of the notice delivered by it to the Company.

            Each certificate or other instrument evidencing the securities
                  issued upon the transfer of any Restricted Securities (and
                  each certificate or other instrument evidencing any
                  untransferred balance of such securities) shall bear the
                  legends set forth in Section 8.1 unless (i) in the opinion of
                  such counsel, registration of future transfer is not required
                  by the applicable provisions of the Securities Act or (ii) the
                  Company shall have waived the requirement of such legends;
                  provided, however, that such legend shall not be required on
                  any certificate or other instrument evidencing the securities
                  issued upon such transfer in the event such transfer shall be
                  made in compliance with the requirements of Rule 144.

            Upon surrender by any Purchaser to the Company of any certificate,
                  representing Purchased Securities, the Company at its expense
                  will, within five business days, issue in exchange therefor,
                  and deliver to the Purchaser, a new certificate or
                  certificates representing such Purchased Securities, in such
                  denominations as may be requested by such Purchaser. Upon
                  receipt of evidence satisfactory to the Company of the loss,
                  theft, destruction or mutilation of any certificate
                  representing any Purchased Securities purchased or acquired by
                  any Purchaser hereunder, and in case of any such loss, theft
                  or destruction, upon delivery of any indemnity agreement
                  satisfactory to the Company, or in any case of any such
                  mutilation, upon surrender and cancellation of such
                  certificate, the Company at its expense will, within five
                  business days, issue and deliver to the Purchaser a new
                  certificate or other instrument for such Purchased Securities
                  of like tenor, in lieu of such lost, stolen, destroyed or
                  mutilated certificate.

            TRANSFER PURSUANT TO RULE 144

The Company covenants that (a) the Company will comply at all times with the
public information requirements of Rule 144(c)(1); and (b) at all times as Rule
144 is available for use by any Purchaser, the Company will furnish such
Purchaser, upon its request, with all information within the possession of the
Company reasonably required for the preparation and filing of Form 144.

MISCELLANEOUS COVENANTS

            CERTAIN TAXES

The Company shall pay, and will hold each Purchaser harmless from, (a) any and
all liability with respect to any transfer, transfer gains, stamp or similar
Taxes which may be determined to be payable in connection with (i) the execution
and delivery and performance of this Agreement

automated quotation system on the date any registration statement filed by the
Company pursuant to the Registration Rights Agreement becomes effective, the
Company will promptly secure the listing of the shares of Common Stock issuable
upon conversion of the Purchased Shares or upon exercise of the Purchased
Warrants upon each national securities exchange or automated quotation system
upon which shares of Common Stock are then listed. The Company represents and
warrants that it has taken no action designed to delist, or which is likely to

                  their respective heirs, successors, and permitted assigns,
                  except that the Company shall not assign its rights or
                  obligations hereunder without the consent of the Purchasers
                  holding a majority of the Purchased Shares issued hereunder.

            Each Purchaser shall have the right, without the consent of the
                  Company but subject to compliance with applicable securities
                  laws and the applicable provisions of this Agreement and the
                  other Transaction Documents, to assign, all or part of, the
                  securities acquired by it hereunder (including securities into
                  which or for which such securities are convertible,
                  exchangeable or exercisable) and assign, all or part of, its
                  rights and obligations under this Agreement or any of the
                  other Transaction Documents. The Company shall promptly amend
                  Annex I to reflect the notice information for each transferee
                  thereof as contemplated by Section 11. Upon any such
                  amendment, the Company shall promptly deliver a copy of such
                  Annex I, as so amended, to each Purchaser.

            COUNTERPARTS

This Agreement may be executed in any number of counterparts, and each such
counterpart shall be deemed to be an original instrument, but all such
counterparts together shall constitute but one agreement. Counterparts
transmitted by facsimile may be treated as an original instrument and relied
upon for all purposes as such.

            GOVERNING LAW; WAIVER OF JURY TRIAL; CONSENT TO JURISDICTION

            All questions concerning the construction, interpretation and
                  validity of this Agreement shall be governed by and construed
                  and enforced in accordance with the internal law of the State
                  of Ohio, without giving effect to any choice or conflict of
                  law provision or rule (whether in the State of Ohio or any
                  other jurisdiction) that would cause the application of the
                  law of any jurisdiction other than the State of Ohio. In
                  furtherance of the foregoing, the internal law of the State of
                  Ohio will control the interpretation and construction of this
                  Agreement, even if under such jurisdiction's choice of law or
                  conflict of law analysis, the internal law of some other
                  jurisdiction would ordinarily or necessarily apply.

            BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX FINANCIAL
                  TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN
                  EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE
                  LAWS TO APPLY (RATHER THAN ARBITRATION RULES), THE PARTIES
                  DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING
                  SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST
                  COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF
                  ARBITRATION, THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY
                  JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO ENFORCE OR
                  DEFEND ANY RIGHTS OR REMEDIES UNDER THIS AGREEMENT OR ANY
                  DOCUMENTS RELATED HERETO.

            Each of the parties hereto hereby irrevocably and unconditionally
                  submits, for itself and its property, to the non-exclusive
                  jurisdiction of any court of the State of Ohio or federal
                  court of the United States of America sitting in the State of
                  Ohio, and any appellate court from any thereof, in any action
                  or proceeding arising out of or relating to this Agreement or
                  for recognition or enforcement of any judgment, and each of
                  the parties hereto hereby irrevocably and unconditionally
                  agrees that all claims in respect of any such action or
                  proceeding may be heard and determined in any such court of
                  the State of Ohio or, to the extent permitted by law, in such
                  federal court. Each of the parties hereto agrees that a final
                  judgment in any such action or proceeding shall be conclusive
                  and may be enforced in other jurisdictions by suit on the
                  judgment or in any other manner provided by law.

            Each of the parties hereto irrevocably and unconditionally waives,
                  to the fullest extent it may legally and effectively do so,
                  any objection that it may now or hereafter have to the laying
                  of venue of any suit, action or proceeding arising out of or
                  relating to this Agreement in any court of the State of Ohio
                  or federal court sitting in the State of Ohio. Each of the
                  parties hereto irrevocably waives, to the fullest extent
                  permitted by law, the defense of an inconvenient forum to the
                  maintenance of such action or proceeding in any such court.

            WAIVERS AND AMENDMENTS

            No failure or delay of any of the Purchasers in exercising any power
                  or right in this Agreement or in any other Transaction
                  Document shall operate as a waiver hereof or thereof, nor
                  shall any single or partial exercise of any such right or
                  power, or any abandonment or discontinuance of steps to
                  enforce such right or power, preclude any other or further
                  exercise of any other right or power. No waiver of any
                  provision of this Agreement or any other Transaction Document
                  or consent to any departure by the Company therefrom shall in
                  any event be effective unless the same shall be authorized as
                  provided for in Section 12.6(b), and then such waiver or
                  consent shall be effective only in the specific instance and
                  for the purpose

<PAGE>

                  for which given. No notice or demand on the Company in any
                  case shall entitle the Company to any other or further notice
                  or demand in similar or other circumstances.

            Except as provided in Section 12.3, neither this Agreement nor any
                  provision hereof may be waived, amended or modified except
                  pursuant to a written instrument which specifically references
                  this Agreement which has been signed by the party against whom
                  such waiver, amendment or modification is sought to be
                  enforced or such party's authorized officer or representative.

rewritten herein.

            INTERPRETATION AND CONSTRUCTION

The term "this Agreement" means this Series B Convertible Preferred Stock and
Warrant Purchase Agreement, together with all annexes, schedules and exhibits
hereto, as the same may from time to time be amended, modified, supplemented or
restated in accordance with the terms hereof. Accounting terms used but not
otherwise defined herein shall have the meanings given to them under GAAP. The
use in this Agreement of the term "including" means "including, without
limitation." The words "herein," "hereof," "hereunder" and other words of
similar import refer to this Agreement as a whole, including its annexes,
schedules and exhibits, as the same may from time to time be amended, modified,
supplemented or restated, and not to any particular section, subsection,
paragraph, subparagraph or clause contained in this Agreement. All references to
sections, annexes, schedules and exhibits mean the sections of this Agreement
and the annexes, schedules and exhibits attached to this Agreement, except where
otherwise stated. The title of and the section and paragraph headings in this

the interpretation of any of the terms or provisions of this Agreement. The use
herein of the masculine, feminine or neuter forms shall also denote the other
forms, as in each case the context may require or permit. Where specific
language is used to clarify by example a general statement contained herein,
such specific language shall not be deemed to modify, limit or restrict in any
manner the construction of the general statement to which it relates. The
language used in this Agreement has been chosen by the parties to express their
mutual intent, and no rule of strict construction shall be applied against any
party. All references to payment amounts herein are United States dollar
amounts, and all payments hereunder shall be made in United States dollars.
Unless expressly provided otherwise, the measure of a period of one month or

exists, the measure shall be that date of the following month or year
corresponding to the next day following the starting date. For example, one
month following February 18 is March 18, and one month following March 31 is May
1.

            NO FIDUCIARY RELATIONSHIP

course of dealing among the parties hereto shall be deemed to create any
fiduciary duty by any of the Purchasers or any of their respective affiliates to
the Company or its directors, officers, employees, stockholders or affiliates.

SEVERABILITY

It is the desire and intent of the parties that the provisions of this Agreement
be enforced to the fullest extent permissible under the laws and public policies
applied in each jurisdiction in which enforcement is sought. Accordingly, if any
particular provision of this Agreement shall be adjudicated by a court of
competent jurisdiction to be invalid, prohibited or unenforceable for any
reason, such provision, as to such jurisdiction, shall be ineffective, without
invalidating the remaining provisions of this Agreement or affecting the
validity or enforceability of this Agreement or affecting the validity or
enforceability of such provision in any other jurisdiction. Notwithstanding the
foregoing, if such provision could be more narrowly drawn so as not to be
invalid, prohibited or unenforceable in such jurisdiction, it shall, as to such
jurisdiction, be so narrowly drawn, without invalidating the remaining
provisions of this Agreement or affecting the validity or enforceability of such
provision in any other jurisdiction.
