value per share, of which 8,780,050 shares are issued and outstanding, 1,000

no outstanding Capital Shares Equivalents nor any agreements or understandings
pursuant to which any Capital Shares Equivalents may become outstanding. The

of the outstanding shares of Common Stock of the Company have been duly and
validly authorized and issued and are fully paid and non-assessable.

pursuant to Section 12(b) or (g) of the Exchange Act and is in full compliance
with all reporting requirements of the Exchange Act, and the Company is in
compliance with all requirements for the continued listing or quotation of its
Common Stock, and such Common Stock is currently listed or quoted on, the
Principal Market. As of the date hereof, the Principal Market is the NASDAQ

<PAGE>   10


their respective dates, the SEC Documents complied in all material respects
with the requirements of the Exchange Act, and rules and regulations of the SEC
promulgated thereunder and the SEC Documents did not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading. The financial
statements of the Company included in the SEC Documents complied in all
material respects with applicable accounting requirements and the published
rules and regulations of the SEC or other applicable rules and regulations with
respect thereto at the time of such inclusion. Such financial statements have
been prepared in accordance with generally accepted accounting principles
applied on a consistent basis during the periods involved (except (i) as may be
otherwise indicated in such financial statements or the notes thereto or (ii)
in the case of unaudited interim statements, to the extent they exclude
footnotes or may be condensed or summary statements) and fairly present in all
material respects the financial position of the Company as of the dates thereof
and the results of operations and cash flows for the periods then ended
(subject, in the case of unaudited interim statements, to normal year-end audit
adjustments). Neither the Company nor any of its subsidiaries has any material
indebtedness, obligations or liabilities of any kind (whether accrued,
absolute, contingent or otherwise, and whether due or to become due) that would
have been required to be reflected in, reserved against or otherwise described
in the financial statements or in the notes thereto in accordance with GAAP,
which was not fully reflected in, reserved against or otherwise described in
the financial statements or the notes thereto included in the SEC Documents or
was not incurred in the ordinary course of business consistent with the
Company's past practices since the last date of such financial statements.

Section 4.6.      Exemption from Registration; Valid Issuances. Subject to the
accuracy of the Investors' representations in Article III, the sale of the
Shares and the Warrants will not require registration under the Securities Act
and/or any applicable state securities law. Neither the sales of the Shares nor
the Company's performance of its obligations under this Agreement, the
Registration Rights Agreement, the Escrow Agreement or the Warrants will (i)
result in the creation or imposition by the Company of any liens, charges,
claims or other encumbrances upon the Shares or, except as contemplated herein,
any of the assets of the Company, or (ii) entitle the holders of Outstanding
Capital Shares to preemptive or other rights to subscribe for or acquire the
Capital Shares or other securities of the Company. The Shares shall not subject
the Investors to personal liability to the Company or its creditors by reason
of the possession thereof.

Section 4.7.      No General Solicitation or Advertising in Regard to this
Transaction. Neither the Company nor any of its affiliates nor, to the
knowledge of the Company, any person acting on its or their behalf (i) has
conducted or will conduct any general solicitation (as that term is used in
Rule 502(c) of Regulation D) or general advertising with respect to the sale of
the Shares or the Warrants, or (ii) made any offers or sales of any security or
solicited any offers to buy any security under any circumstances that would
require registration of the Shares or the Warrants under the Securities Act.

Agreement by the Company and the consummation by the Company of the
transactions contemplated hereby, including without limitation the issuance of
the Shares and the Warrants, do not and will not (i) result in a violation of
the Company's Certificate of Incorporation or By-Laws or (ii) conflict

with, or constitute a material default (or an event that with notice or lapse
of time or both would become a default) under, or give to others any rights of
termination, amendment, acceleration or cancellation of, any material
agreement, indenture or instrument, or any "lock-up" or similar provision of
any underwriting or similar agreement to which the Company is a party, or (iii)
result in a violation of any federal, state or local law, rule, regulation,
order, judgment or decree (including federal and state securities laws and
regulations) applicable to the Company or by which any material property or
asset of the Company is bound or affected, nor is the Company otherwise in
violation of, conflict with or default under any of the foregoing (except in
each case for such conflicts, defaults, terminations, amendments,
accelerations, cancellations and violations as would not have, individually or
in the aggregate, a Material Adverse Effect). The business of the Company is
not being conducted in violation of any law, ordinance or regulation of any
governmental entity, except for possible violations that either singly or in
the aggregate would not have a Material Adverse Effect. The Company is not
required under any Federal, state or local law, rule or regulation to obtain
any consent, authorization or order of, or make any filing or registration
with, any court or governmental agency in order for it to execute, deliver or
perform any of its obligations under this Agreement or issue and sell the
Shares in accordance with the terms hereof (other than any SEC or state
securities filings that may be required to be made by the Company subsequent to
each Closing, any registration statement that may be filed pursuant hereto);
provided that, for purposes of the representation made in this sentence, the
Company is assuming and relying upon the accuracy of the relevant
representations and agreements of the Investors herein.

Section 4.9.      No Material  Adverse Change.  Since  September 30, 1999, no
Material Adverse Effect has occurred or exists with respect to the Company.

Section 4.10.     No Undisclosed Events or Circumstances. Since September 30,
1999, no event or circumstance has occurred or exists with respect to the
Company or its businesses, properties, prospects, operations or financial
condition, that, under applicable law, rule or regulation, requires public
disclosure or announcement prior to the date hereof by the Company but which
has not been so publicly announced or disclosed in the SEC Documents.

Section 4.11.     No Integrated Offering. Other than pursuant to an effective
registration statement under the Securities Act, or pursuant to the issuance or
exercise of employee stock options, or pursuant to its discussion with the
Investors in connection with the transactions contemplated hereby, the Company
has not issued, offered or sold its Common Stock, or any securities convertible
into or exchangeable or exercisable for Common Stock within the six-month
period next preceding the date hereof, and the Company shall not permit any of
its directors, officers or affiliates directly or indirectly to take, any
action (including, without limitation, any offering or sale to any Person of
the Shares and Warrants), so as to make unavailable the exemption from
Securities Act registration being relied upon by the Company for the offer and
sale to Investors of the Shares and Warrants as contemplated by this Agreement.

Section 4.12.     Litigation and Other Proceedings. There are no lawsuits or
proceedings pending or, to the knowledge of the Company, threatened, against
the Company or any subsidiary, nor has the Company received any written or oral
notice of any such action, suit, proceeding or investigation, which could
reasonably be expected to have a Material Adverse Effect. No judgment, order,
writ, injunction or decree or award has been issued by or, to the knowledge of


                                      10
<PAGE>   12


the Company, requested of any court, arbitrator or governmental agency which
could result in a Material Adverse Effect.

Section 4.13.     No Misleading or Untrue Communication. The Company and, to
the knowledge of the Company, any person representing the Company, or any other
person selling or offering to sell the Shares and Warrants in connection with
the transaction contemplated by this Agreement, have not made, at any time, any
oral communication in connection with the offer or sale of the same which
contained any untrue statement of a material fact or omitted to state any
material fact necessary in order to make the statements, in the light of the
circumstances under which they were made, not misleading.

Section 4.14.     Material Non-Public Information. The Company has not
disclosed to the Investors any material non-public information that (i) if
disclosed, would reasonably be expected to have a material effect on the price
of the Common Stock or (ii) according to applicable law, rule or regulation,
should have been disclosed publicly by the Company prior to the date hereof but
which has not been so disclosed.

Section 4.15.     Insurance. The Company and each subsidiary maintains
property and casualty, general liability, workers' compensation, environmental
hazard, personal injury and other similar types of insurance with financially
sound and reputable insurers that is adequate, consistent with industry
standards and the Company's historical claims experience. The Company has not
received notice from, and has no knowledge of any threat by, any insurer (that
has issued any insurance policy to the Company) that such insurer intends to
deny coverage under or cancel, discontinue or not renew any insurance policy
presently in force.

Section 4.16.     Tax Matters.

         (a)      The Company and each subsidiary has filed all Tax Returns
which it is required to file under applicable laws; all such Tax Returns are
true and accurate in all material respects and has been prepared in compliance
with all applicable laws in all material respects; the Company has paid all
Taxes due and owing by it or any subsidiary (whether or not such Taxes are
required to be shown on a Tax Return) and have withheld and paid over to the
appropriate taxing authorities all Taxes which it is required to withhold from
amounts paid or owing to any employee, stockholder, creditor or other third
parties; and since December 31, 1998, the charges, accruals and reserves for
Taxes with respect to the Company (including any provisions for deferred income
taxes) reflected on the books of the Company are to the knowledge of the
Company adequate to cover any Tax liabilities of the Company if its current tax
year were treated as ending on the date hereof.

         (b)      To the knowledge of the Company, no claim has been made by a
taxing authority in a jurisdiction where the Company does not file tax returns
that the Company or any subsidiary is or may be subject to taxation by that
jurisdiction. There are no foreign, federal, state or local tax audits or
administrative or judicial proceedings pending or being conducted with respect
to the Company or any subsidiary; no information related to Tax matters has
been requested by any foreign, federal, state or local taxing authority; and,
except as disclosed above, no written notice indicating an intent to open an
audit or other review has been received by the Company or any subsidiary from
any foreign, federal, state or local taxing authority. There are no material

extent that the Indemnifying Party is actually prejudiced by such omission or
delay. In connection with any Claim as to which both


                                      16
<PAGE>   18


the Indemnifying Party and the Indemnified Party are parties, the Indemnifying
Party shall be entitled to assume the defense thereof. Notwithstanding the
assumption of the defense of any Claim by the Indemnifying Party, the
Indemnified Party shall have the right to employ separate legal counsel and to
participate in the defense of such Claim, and the Indemnifying Party shall bear
the reasonable fees, out-of-pocket costs and expenses of such separate legal
counsel to the Indemnified Party if (and only if): (x) the Indemnifying Party
shall have agreed to pay such fees, out-of-pocket costs and expenses, (y) the
Indemnified Party reasonably shall have concluded that representation of the
Indemnified Party and the Indemnifying Party by the same legal counsel would
not be appropriate due to actual or, as reasonably determined by legal counsel
to the Indemnified Party, potentially differing interests between such parties
in the conduct of the defense of such Claim, or if there may be legal defenses
available to the Indemnified Party that are in addition to or disparate from
those available to the Indemnifying Party, or (z) the Indemnifying Party shall
have failed to employ legal counsel reasonably satisfactory to the Indemnified
Party within a reasonable period of time after notice of the commencement of
such Claim. If the Indemnified Party employs separate legal counsel in
circumstances other than as described in clauses (x), (y) or (z) above, the
fees, costs and expenses of such legal counsel shall be borne exclusively by
the Indemnified Party. Except as provided above, the Indemnifying Party shall
not, in connection with any Claim in the same jurisdiction, be liable for the
fees and expenses of more than one firm of legal counsel for the Indemnified
Party (together with appropriate local counsel). Neither the Indemnifying Party
nor the Indemnified Party shall, without the prior written consent of the
Indemnified Party or the Indemnifying Party, as applicable (which consent shall
not unreasonably be withheld), settle or compromise any Claim or consent to the
entry of any judgment that does not include an unconditional release of the
Indemnified Party or the Indemnifying Party, as applicable, from all
liabilities with respect to such Claim or judgment.

                  All fees and expenses of the Indemnified Party (including
reasonable costs of defense and investigation in a manner not inconsistent with
this Section and all reasonable attorneys' fees and expenses) shall be paid to
the Indemnified Party, as incurred, within ten (10) Trading Days of written
notice thereof to the Indemnifying Party (regardless of whether it is
ultimately determined that an indemnified party is not entitled to
indemnification hereunder; provided, that the Indemnifying Party may require
such Indemnified Party to undertake to reimburse all such fees and expenses to
the extent it is finally judicially determined that such Indemnified Party is
not entitled to indemnification hereunder).

Section 7.4.      Direct Claims. In the event one party hereunder should have a
claim for indemnification that does not involve a claim or demand being
asserted by a third party, the Indemnified Party promptly shall deliver notice
of such claim to the Indemnifying Party. If the Indemnified Party disputes the
claim, such dispute shall be resolved by mutual agreement of the Indemnified
Party and the Indemnifying Party or by binding arbitration conducted in
accordance with the procedures and rules of the American Arbitration
Association as set forth in Article X. Judgment upon any award rendered by any
arbitrators may be entered in any court having competent jurisdiction thereof.

        DUE DILIGENCE REVIEW; NON-DISCLOSURE OF NON-PUBLIC INFORMATION.


Section 8.1.      Due Diligence Review. Subject to Section 8.2, the Company
shall make available for inspection and review by the Investors, advisors to
and representatives of the Investors (who may or may not be affiliated with the
Investors and who are reasonably acceptable to the Company), any underwriter
participating in any disposition of the Registrable Securities on behalf of the
Investors pursuant to the Registration Statement, any such registration
statement or amendment or supplement thereto or any blue sky, Nasdaq or other
filing, all SEC Documents and other filings with the SEC, and all other
publicly available corporate documents and properties of the Company as may be
reasonably necessary for the purpose of such review, and cause the Company's
officers, directors and employees to supply all such publicly available
information reasonably requested by the Investors or any such representative,
advisor or underwriter in connection with such Registration Statement
(including, without limitation, in response to all questions and other
inquiries reasonably made or submitted by any of them), prior to and from time
to time after the filing and effectiveness of the Registration Statement for
the sole purpose of enabling the Investors and such representatives, advisors
and underwriters and their respective accountants and attorneys to conduct
initial and ongoing due diligence with respect to the Company and the accuracy
of the Registration Statement.

Section 8.2.      Non-Disclosure of Non-Public Information.

         (a)      The Company shall not disclose material non-public
information to the Investors, advisors to or representatives of the Investors
unless prior to disclosure of such information the Company identifies such
information as being non-public information and provides the Investors, such
advisors and representatives with the opportunity to accept or refuse to accept
such non-public information for review. Other than disclosure of any comment
letters received from the SEC staff with respect to the Registration Statement,
the Company may, as a condition to disclosing any non-public information
hereunder, require the Investors' advisors and representatives to enter into a
confidentiality agreement in form and content reasonably satisfactory to the
Company and the Investors.

         (b)      Nothing herein shall require the Company to disclose material
non-public information to the Investors or their advisors or representatives,
and the Company represents that it does not disseminate material non-public
information to any Investors who purchase stock in the Company in a public
offering, to money managers or to securities analysts, provided, however, that
notwithstanding anything herein to the contrary, the Company will, as
hereinabove provided, promptly notify the advisors and representatives of the
Investors and, if any, underwriters, of any event or the existence of any
circumstance (without any obligation to disclose the specific event or
circumstance) of which it becomes aware, constituting material non-public
information (whether or not requested of the Company specifically or generally
during the course of due diligence by such persons or entities), which, if not
disclosed in the prospectus included in the Registration Statement would cause
such prospectus to include a material misstatement or to omit a material fact
required to be stated therein in order to make the statements, therein in light
of the circumstances in which they were made, not misleading. Nothing contained
in this Section 8.2 shall be construed to mean that such persons or entities
other than the Investors (without the written consent of the Investors prior to
disclosure of such


                                      18
<PAGE>   20


information as set forth in Section 8.2(a)) may not obtain non-public
information in the course of conducting due diligence in accordance with the
terms of this Agreement and nothing herein shall prevent any such persons or
entities from notifying the Company of their opinion that based on such due
diligence by such persons or entities, that the Registration Statement contains
an untrue statement of a material fact or omits a material fact required to be
stated in the Registration Statement or necessary to make the statements
contained therein, in light of the circumstances in which they were made, not
misleading.


                                  ARTICLE IX

                      LEGENDS; TRANSFER AGENT INSTRUCTIONS


Section 9.1.      Legends. Unless otherwise provided below, each certificate
representing Registrable Securities will bear the following legend or
equivalent (the "Legend"):

THE SECURITIES EVIDENCED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE
U.S. SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR ANY OTHER
APPLICABLE SECURITIES LAWS AND HAVE BEEN ISSUED IN RELIANCE UPON AN EXEMPTION
FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND SUCH OTHER
SECURITIES LAWS. NEITHER THIS SECURITY NOR ANY INTEREST OR PARTICIPATION HEREIN
MAY BE SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED, OR OTHERWISE DISPOSED
OF, EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES
ACT OR PURSUANT TO A TRANSACTION THAT IS EXEMPT FROM SUCH REGISTRATION.

Section 9.2.      Transfer Agent Instructions. Upon the execution and delivery
hereof, the Company is issuing to the transfer agent for its Common Stock (and
to any substitute or replacement transfer agent for its Common Stock upon the
Company's appointment of any such substitute or replacement transfer agent)
instructions substantially in the form of Exhibit E hereto. Such instructions
shall be irrevocable by the Company from and after the date hereof or from and
after the issuance thereof to any such substitute or replacement transfer
agent, as the case may be.

Section 9.3.      No Other Legend or Stock Transfer Restrictions. No legend
other than the one specified in Section 9.1 has been or shall be placed on the
share certificates representing the Registrable Securities and no instructions
or "stop transfer orders," "stock transfer restrictions," or other restrictions
have been or shall be given to the Company's transfer agent with respect
thereto other than as expressly set forth in this Article IX.

Section 9.4.      Investors' Compliance. Nothing in this Article shall affect
in any way each Investor's obligations to comply with all applicable securities
laws upon resale of the Common Stock.

                           CHOICE OF LAW; ARBITRATION


Section 10.1.     Governing Law/Arbitration. This Agreement shall be governed
by and construed in accordance with the laws of the State of New York
applicable to contracts made in New York by persons domiciled in New York City
and without regard to its principles of conflicts of laws. Any dispute under
this Agreement shall be submitted to arbitration under the American Arbitration
Association (the "AAA") in New York City, New York, and shall be finally and
conclusively determined by the decision of a board of arbitration consisting of
three (3) members (hereinafter referred to as the "Board of Arbitration")
selected according to the rules governing the AAA. The Board of Arbitration
shall meet on consecutive business days in New York City, New York, and shall
reach and render a decision in writing (concurred in by a majority of the
members of the Board of Arbitration) with respect to the amount, if any, which
the losing party is required to pay to the other party in respect of a claim
filed. In connection with rendering its decisions, the Board of Arbitration
shall adopt and follow the laws of the State of New York unless the matter at
issue is the corporation law of the company's state of incorporation, in which
event the corporation law of such jurisdiction shall govern such issue. To the
extent practical, decisions of the Board of Arbitration shall be rendered no
more than thirty (30) calendar days following commencement of proceedings with
respect thereto. The Board of Arbitration shall cause its written decision to
be delivered to all parties involved in the dispute. Any decision made by the
Board of Arbitration (either prior to or after the expiration of such thirty
(30) calendar day period) shall be final, binding and conclusive on the parties
to the dispute, and entitled to be enforced to the fullest extent permitted by
law and entered in any court of competent jurisdiction. The Board of
Arbitration shall be authorized and is hereby directed to enter a default
judgment against any party failing to participate in any proceeding hereunder
within the time periods set forth in the AAA rules. The prevailing party shall
be awarded its costs, including attorneys' fees, from the non-prevailing party
as part of the arbitration award. Any party shall have the right to seek
injunctive relief from any court of competent jurisdiction in any case where
such relief is available. The prevailing party in such injunctive action shall
be awarded its costs, including attorney's fees, from the non-prevailing party.


                                  ARTICLE XI

                                   ASSIGNMENT

Investors or the Company hereunder may be assigned by either party to any other
person.

<PAGE>   23


Section 13.1.     Counterparts/ Facsimile/ Amendments. This Agreement may be
executed in multiple counterparts, each of which may be executed by less than
all of the parties and shall be deemed to be an original instrument which shall
be enforceable against the parties actually executing such counterparts and all
of which together shall constitute one and the same instrument. Except as
otherwise stated herein, in lieu of the original documents, a facsimile
transmission or copy of the original documents shall be as effective and
enforceable as the original. This Agreement may be amended only by a writing
executed by all parties.

Section 13.2.     Entire Agreement. This Agreement, the agreements attached as
Exhibits hereto, which, include but are not limited the Escrow Agreement, and
the Registration Rights Agreement, set forth the entire agreement and
understanding of the parties relating to the subject matter hereof and
supersedes all prior and contemporaneous agreements, negotiations and
understandings between the parties, both oral and written relating to the
subject matter hereof. The terms and conditions of all Exhibits to this
Agreement are incorporated herein by this reference and shall constitute part
of this Agreement as is fully set forth herein.

Section 13.3.     Severability. In the event that any provision of this
Agreement becomes or is declared by a court of competent jurisdiction to be
illegal, unenforceable or void, this Agreement shall continue in full force and
effect without said provision; provided that such severability shall be
ineffective if it materially changes the economic benefit of this Agreement to
any party.

Section 13.4.     Headings. The headings used in this Agreement are used for
convenience only and are not to be considered in construing or interpreting
this Agreement.

Section 13.5.     Number and Gender. There may be one or more Investors parties
to this Agreement, which Investors may be natural persons or entities. All
references to plural Investors shall apply equally to a single Investor if
there is only one Investor, and all references to an Investor as "it" shall
apply equally to a natural person.

Section 13.6.     Replacement of Certificates. Upon (i) receipt of evidence
reasonably satisfactory to the Company of the loss, theft, destruction or
mutilation of a certificate representing the Shares and (ii) in the case of any
such loss, theft or destruction of such certificate, upon delivery of an
indemnity agreement or security reasonably satisfactory in form to the Company
(which shall not include the posting of any bond) or (iii) in the case of any
such mutilation, on surrender and cancellation of such certificate, the Company
at its expense will execute and deliver, in lieu thereof, a new certificate of
like tenor.

Section 13.7.     Fees and Expenses. Each of the Company and the Investors
agrees to pay its own expenses incident to the performance of its obligations
hereunder.

Section 13.8.     Brokerage. Each of the parties hereto represents that it has
had no dealings in connection with this transaction with any finder or broker
who will demand payment of any fee or commission from the other party, except
Ladenburg Thalmann & Co. Inc. whose fees shall be paid by the Company. The
Company on the one hand, and the Investors, on the other hand, agree to
indemnify the other against and hold the other harmless from any and all
liabilities to any person claiming brokerage commissions or finder's fees on
account of services purported to


                                      22
<PAGE>   24


have been rendered on behalf of the indemnifying party in connection with this
Agreement or the transactions contemplated hereby.

Section 13.9.     Publicity. The Company agrees that, except as required by law
or regulation, it will not issue any press release or other public announcement
of the transactions contemplated by this Agreement without the prior consent of
the Investors, which shall not be unreasonably withheld nor delayed by more
than two (2) Trading Days from their receipt of such proposed release. No
release shall name the Investors without their express consent.

Section 13.10.    No Third Party Beneficiary. The terms and provisions of this
Agreement are intended solely for the benefit of each party and their
respective successors or permitted assigns. It is not the intention of the
parties to confer third-party beneficiary rights and this Agreement does not
confer any such rights upon any other person other than a party to this
Agreement.
