Exhibit 10.2


                             SUBSCRIPTION AGREEMENT

            THIS SUBSCRIPTION AGREEMENT (the "Agreement") is made as of the date
set forth on the signature page hereof between Nephros, Inc., a Delaware
corporation (the "Company"), and the undersigned (the "Subscriber").

                              W I T N E S S E T H:

            WHEREAS, the Company desires to issue $5,500,000 of Series A
Convertible Preferred Stock, par value $.001 per share, of the Company (the
"Preferred Stock" and collectively with the common stock underlying the
Preferred Stock hereinafter sometimes collectively referred to as the
"Securities") in a private placement of the Company's securities (the
"Offering");

            WHEREAS, the Subscriber desires to purchase that number of shares of
Preferred Stock set forth on the signature page hereof on the terms and
conditions hereinafter set forth;

            NOW, THEREFORE, in consideration of the premises and the mutual
representations and covenants hereinafter set forth, the parties hereto do
hereby agree as follows:

I     SUBSCRIPTION FOR PREFERRED STOCK AND REPRESENTATIONS BY SUBSCRIBER

      1     Subject to the terms and conditions hereinafter set forth, the
            Subscriber hereby subscribes for and agrees to purchase from the
            Company such number of shares of Preferred Stock (the "Shares") as
            set forth upon the signature page hereof at a price equal to $1.25
            per Share and the Company agrees to sell such Shares to the
            Subscriber for said purchase price. Upon drawdown by the Company in
            accordance with Article III of this Agreement, the purchase price
            attributable to such drawdown will be payable by personal or
            business check, wire transfer of immediately available funds or
            money order made payable to "Nephros, Inc." The certificates
            representing the Securities will be delivered by the Company to the
            Subscriber within ten (10) business days following the receipt of
            Subscriber's payment of the applicable drawdown amount.

      2     The Subscriber recognizes that the purchase of the Preferred Stock
            involves a high degree of risk in that, among other things, (i) the
            Company is a development stage business with no operating history
            and requires substantial funds in addition to the proceeds of the
            Offering; (ii) an investment in the Company is highly speculative,
            and only investors who can afford the loss of their entire
            investment should consider investing in the Company and the
            Preferred Stock; (iii) the Subscriber may not be able to liquidate
            the Subscriber's investment; (iv) transferability of the Securities
            is extremely limited and (v) in the event of a disposition, the
            Subscriber could sustain the loss of the Subscriber's entire
            investment.

      3     The Subscriber represents that the Subscriber is an "accredited
            investor," as such term is defined in Rule 501 of Regulation D
            promulgated under the Securities Act





            of 1933, as amended (the "Act"), as indicated by his responses to
            the questions contained in Article VI hereof, and that the
            Subscriber is able to bear the economic risk of an investment in the
            Preferred Stock. The Subscriber covenants to notify the Company at
            any time prior to the second drawdown (as defined in Article 3) if
            it is no longer an "accredited investor."

      4     The Subscriber hereby acknowledges and represents that (i) the
            Subscriber has prior investment experience, including investment in
            non-listed and unregistered securities, or, to the extent necessary,
            the Subscriber has employed at its own expense and relied upon the
            services of an investment advisor, attorney and/or accountant to
            read all of the documents furnished or made available by the Company
            both to the Subscriber and to all other prospective investors in the
            Preferred Stock and to evaluate the investment, tax and legal merits
            and the consequences and risks of such an investment on the
            Subscriber's behalf; (ii) the Subscriber recognizes the highly
            speculative nature of this investment, and (iii) the Subscriber is
            able to bear the economic risk which the Subscriber hereby assumes.

      5     The Subscriber hereby acknowledges receipt and careful review of the
            Confidential Term Sheet dated July 15, 1997 and the attachments and
            exhibits thereto, all of which constitute an integral part thereof
            (the "Term Sheet"). The Subscriber further represents that it has
            been furnished by the Company during the course of this transaction
            with all information regarding the Company which the Subscriber has
            requested or desired to know, has been afforded the opportunity to
            ask questions of and receive answers from duly authorized officers
            or other representatives of the Company concerning the terms and
            conditions of the Offering and has received any additional
            information which the Subscriber has requested.

      6     (a) The Subscriber has relied solely upon the information provided
            by the Company in the Term Sheet in making the decision to invest in
            the Preferred Stock and the Subscriber covenants that no person
            other than the Company has supplied the Subscriber with any
            information relating to an investment in the Preferred Stock.

            (b) The Subscriber covenants that no Preferred Stock was offered or
            sold to it by means of any form of general solicitation or general
            advertising, and in connection therewith the Subscriber did not (A)
            receive or review any advertisement, article, notice or other
            communication published in a newspaper or magazine or similar media
            or broadcast over television or radio whether closed circuit or
            generally available, or (B) attend any seminar meeting or industry
            investor conference whose attendees were invited by any general
            solicitation or general advertising.

      7     The Subscriber agrees that the Subscriber will not sell or otherwise
            transfer the Securities unless they are registered under the Act or
            unless an exemption from


                                     - 3 -



            such registration is available and until such Subscriber complies
            with the transfer restrictions set forth in herein.

      8     The Subscriber understands that the Securities have not been
            registered under the Act by reason of a claimed exemption under the
            provisions of the Act which depends, in part, upon the Subscriber's
            investment intention. In connection herewith, the Subscriber hereby
            represents that the Subscriber is purchasing the Securities for the
            Subscriber's own account for investment and not with a view toward
            the resale or distribution to others. The Subscriber, if an entity,
            was not formed for the purpose of purchasing the Securities. The
            Subscriber understands that Rule 144 promulgated under the Act
            requires, among other conditions, a one (1) year holding period
            prior to the resale (in limited amounts) of securities acquired in a
            non-public offering without having to satisfy the registration
            requirements under the Act.

      9     Other than as set forth in Article IV hereof, the Subscriber
            understands and hereby acknowledges that the Company is under no
            obligation to register the shares of common stock (the "Common
            Stock") underlying the Preferred Stock under the Act or any state
            securities or "blue sky" laws. The Subscriber consents that the
            Company may, if it desires, permit the transfer of the Securities
            out of the Subscriber's name only when the Subscriber's request for
            transfer is accompanied by an opinion of counsel reasonably
            satisfactory to the Company that neither the sale nor the proposed
            transfer results in a violation of the Act or any applicable state
            "blue sky" laws (collectively, the "Securities Laws").

      10    The Subscriber agrees to hold the Company and its directors,
            officers, employees, controlling persons and agents and each of
            their respective heirs, representatives, successors and assigns
            harmless and to indemnify them against all liabilities, costs and
            expenses incurred by them as a result of any misrepresentation made
            by the Subscriber contained in this Agreement (including the
            Confidential Investor Questionnaire contained in Article VI herein)
            or any sale or distribution by the Subscriber in violation of the
            Securities Laws.

      11    The Subscriber consents to the placement of a legend on any
            certificate, or other document evidencing the Securities, that such
            Securities have not been registered under the Securities Laws and
            setting forth or referring to the restrictions on transferability
            and sale thereof contained in this Agreement. The Subscriber is
            aware that the Company will make a notation in its appropriate
            records with respect to the restrictions on the transferability of
            such Securities.

      12    The Subscriber understands that the Company will review this
            Agreement and the Company is hereby given authority by the
            Subscriber to call the Subscriber's bank or place of employment or
            otherwise review the financial standing of the Subscriber; and it is
            further agreed that the Company reserves the unrestricted right,
            without further documentation or agreement on the part of the
            Subscriber, to reject all or a portion of any subscription, to
            accept subscriptions for lesser amounts than subscribed for and to
            close the Offering to the Subscriber at any


                                     - 4 -



            time. In addition, the Subscriber understands and agrees that the
            during the Drawdown Period (as hereinafter defined), the Subscriber
            shall have no rights in or to purchase Securities and the Company,
            in its sole discretion, shall have the right to drawdown in whole or
            in part or to cancel any subscription.

      13    The Subscriber hereby represents that the address of the Subscriber
            furnished by the Subscriber on the signature page hereof is the
            Subscriber's principal residence if the Subscriber is an individual
            or its principal business address if it is a corporation or other
            entity.

      14    The Subscriber represents that the Subscriber has full power and
            authority (corporate, statutory and otherwise) to execute and
            deliver this Agreement and to purchase the Preferred Stock. This
            Agreement constitutes the legal, valid and binding obligation of the
            Subscriber, enforceable against the Subscriber in accordance with
            its terms.

      15    If the Subscriber is a corporation, company, trust, employee benefit
            plan, individual retirement account, Keogh Plan, or other tax-exempt
            entity, it is authorized and qualified to become an investor in the
            Company and the person signing this Agreement on behalf of such
            entity has been duly authorized by such entity to do so.

      16    The Subscriber acknowledges that if the Subscriber is a Registered
            Representative of a National Association of Securities Dealers, Inc.
            ("NASD") member firm, the Subscriber must give such firm the notice
            required by the Rules of Fair Practice promulgated by the NASD,
            receipt of which must be acknowledged by such firm in Article 6.4
            below.

II    REPRESENTATIONS BY AND COVENANTS OF THE COMPANY

      1     Organization, Good Standing and Qualification. The Company is a

            currently issued and outstanding and 5,000,000 authorized shares of
            Preferred Stock of which none are currently issued or outstanding.
            All issued and outstanding shares of capital stock of the Company

            no outstanding options, warrants, agreements, convertible
            securities, preemptive rights or other rights to subscribe for or to
            purchase any shares of capital stock of the Company. Except as set
            forth in this


                                     - 5 -



            Agreement and as otherwise required by law, there are no
            restrictions upon the voting or transfer of the Securities pursuant
            to the Company's Certificate of Incorporation, Bylaws or other
            governing documents or any agreement or other instruments to which
            the Company is a party or by which the Company is bound.

      3     Authorization; Enforceability. This Agreement has been duly and
            validly authorized by the Company and is enforceable against the
            Company in accordance with its terms, except as enforceability may
            be limited by applicable bankruptcy, insolvency, reorganization,
            moratorium or similar laws affecting the enforcement of creditors'
            rights generally and by general principles of equity (regardless of
            whether enforcement is sought in a proceeding in equity or at law).
            The Company has full power and lawful authority to authorize, issue
            and sell the Preferred Stock to be sold by it hereunder on the terns

            effecting the conversion of the shares of the Preferred Stock, such
            number of its shares of Common Stock as shall from time to time be
            sufficient to effect the conversion of all outstanding shares of the

            (a)   The execution and delivery by the Company of this Agreement
                  and the consummation of the transactions contemplated hereby
                  will not result in the violation of any law, statute, rule,
                  regulation, order, writ, injunction, judgment or decree of any
                  court or governmental authority to or by which the Company is
                  bound, or of any provision of the Certificate of Incorporation
                  or Bylaws of the Company, and will not conflict with, or
                  result in a breach or violation of, any of the terms or
                  provisions of, or constitute (with due notice or lapse of time
                  or both) a default under, any lease, loan agreement, mortgage,
                  security agreement, trust indenture or other agreement or
                  instrument to which the Company is a party or by which it is

                  governmental authority is required to be obtained by the
                  Company in connection with the authorization, execution and
                  delivery of this Agreement or with the


                                     - 6 -



                  authorization, issue and sale of the Securities, except such
                  filings as may be required to be made with, the Securities and
                  Exchange Commission (the "SEC"), any state or foreign "blue
                  sky" or securities regulatory authority.

      7     Licenses. Except as set forth herein, the Company has sufficient
            licenses, permits and other governmental authorizations currently
            required for the conduct of its business or ownership of properties
            and is in all material respects complying therewith.

      8     Litigation. The Company knows of no pending or threatened legal or
            governmental proceedings against the Company which could materially
            adversely affect the business, property, financial condition or

            the date of each drawdown with the same force and effect as if they
            had been made on and as of such date.

III   TERMS OF SUBSCRIPTION

      1     There will be no minimum commitment amount required for the closing
            of this Offering. Accordingly, the Company may drawdown on
            subscriptions, subject to Article 3.2, immediately following receipt
            of such subscriptions without regard to the aggregate number of
            shares of Preferred Stock subscribed for in the Offering.

      2     The Company shall be permitted to drawdown up to fifty percent (50%)
            of each investors subscription immediately upon acceptance by the
            Company of such subscription and shall be permitted to drawdown the
            remaining fifty percent (50%) of each investors subscription on or
            after the date which is one (1) year from the date of acceptance of
            subscriptions pursuant to this Offering. The Company shall send a
            notice (the "Drawdown Notice") to each Subscriber specifying the
            drawdown amount. The Subscriber shall be required to fund the amount
            specified in the Drawdown Notice within ten (10) business days of
            receipt by the Subscriber of such notice. Any amount of this
            subscription not drawn down upon shall expire on the date which is
            three (3) years from the date of this Agreement (the "Drawdown
            Period").

IV    REGISTRATION RIGHTS

            (b)   The term "Holder" means any person owning or having the right
                  to acquire Registrable Securities or any assignee thereof.

            (c)   The term "1934 Act" shall mean the Securities Exchange Act of
                  1934, as amended.

            (d)   The terms "register", "registered" and "registration" refer to
                  a registration effected by preparing and filing a registration
                  statement or similar document in compliance with the Act, and
                  the declaration or order of effectiveness of such registration
                  statement or document.

            (e)   The term "Registrable Securities" shall mean (i) the shares of
                  Common Stock issuable upon the conversion of the Preferred
                  Stock, (ii) any shares of Common Stock issued as (or issuable
                  upon the conversion or exercise of any warrant, right or other
                  security which is issued as) a dividend or other distribution
                  with respect to or in replacement of the Preferred Stock;
                  provided, however, that securities shall only be treated as
                  Registrable Securities if and only for so long as they (A)
                  have not been disposed of pursuant to a registration statement
                  declared effective by the Commission, (B) have not been sold
                  in a transaction exempt from the registration and prospectus
                  delivery requirements of the Act so that all transfer
                  restrictions and restrictive legends with respect thereto are

            the Company's Common Stock, the Company proposes to register any of
            its stock or other equity securities under the Act in connection
            with the public offering of such securities solely for cash (other
            than a registration relating solely to the sale of securities to
            participants in a Company stock plan, a registration on any form
            which does not include substantially the same information as would
            be required to be included in a registration statement covering the
            sale of the Registrable Securities or a registration in which the
            only Common Stock being registered is Common Stock issuable upon
            conversion of debt securities which are also being registered), the
            Company shall, at such time, promptly give each Holder written
            notice of such registration. Upon the written request of each Holder
            given within ten (10) days after mailing of such notice by the
            Company in accordance with Article 4.1, the Company shall, on up to
            two (2) occasions and subject to the limitations set forth in this
            Agreement (including the provisions of Article 4.8), include in the
            Company's registration statement under the Act all of the
            Registrable Securities that each such Holder has requested to be
            registered; provided, however, that nothing in this Article 4.3
            shall prevent the Company from at any time abandoning or delaying
            any such registration without obligation to any Holder.


                                     - 8 -



      4     Obligations of the Company. Whenever required under this Article IV
            to include Registrable Securities in a Company registration
            statement, the Company shall, as expeditiously as reasonably
            possible:

            (a)   Use its reasonable 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 for a
                  period of up to one hundred twenty (120) days or until the
                  distribution contemplated in the Registration Statement has
                  been completed; provided, however, that such 120-day period
                  shall be extended for a period of time equal to the period
                  that the Holder refrains from selling any securities included
                  in such registration at the request of an underwriter of
                  Common Stock (or other securities) of the Company, and
                  provided further that if applicable rules under the Act
                  governing the obligation to file a post-effective amendment
                  permits, in lieu of filing a post-effective amendment which
                  (x) includes any prospectus required by Section 10(a)(3) of
                  the Act or (y) reflects facts or events representing a
                  material or fundamental change in the information set forth in
                  the registration statement, the Company may incorporate by
                  reference information required to be included in (x) and (y)
                  above to the extent such information is contained in periodic
                  reports filed pursuant to Section 13 or 15(d) of the 1934 Act
                  in the registration statement.

            (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 Act with
                  respect to the disposition of all securities covered by such
                  registration statement.

            (c)   Furnish to the Holders such numbers of copies of a prospectus,
                  including a preliminary prospectus, in conformity with the
                  requirements of the 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 reasonable 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, unless the Company is already subject to
                  service in such jurisdiction and except as may be required by
                  the Act.

            (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 of
                  such offering. Each Holder


                                     - 9 -



                  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 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 in the
                  light of the circumstances then existing.

            (g)   Cause all such Registrable Securities registered hereunder to
                  be listed on each securities exchange on which similar
                  securities issued by the Company are then listed.

            (h)   Provide a transfer agent and registrar for all Registrable
                  Securities registered pursuant hereunder and CUSIP number for
                  all such Registrable Securities, in each case not later than
                  the effective date of such registration.

      5     Furnish Information. It shall be a condition precedent to the
            obligation of the Company to take any action pursuant to this
            Article IV with respect to the Registrable Securities of any selling
            Holder that such Holder shall furnish to the Company such
            information regarding the Holder, the Registrable Securities held by
            the Holder, and the intended method of disposition of such
            securities as shall be required to effect the registration of such
            Holder's Registrable Securities.

      6     Expenses of Company Registration. The Company shall bear and pay all
            expenses incurred in connection with any registration, filing or
            qualification of Registrable Securities with respect to the
            registrations pursuant to Article 4.3 for each Holder, including
            (without limitation) all registration, filing, and qualification
            fees, printers and accounting fees relating or apportionable
            thereto, but excluding underwriting discounts and commissions
            relating to Registrable Securities; provided, however, that the
            Company shall not bear the cost of any professional fees or costs of
            accounting, financial or legal advisors to any of the Holders.
            Notwithstanding the foregoing, each Holder shall pay all
            registration expenses which such Holder is required to pay under
            applicable law.

      7     Underwriting Requirements. In connection with any offering involving
            an underwriting of shares of the Company's capital stock, the
            Company shall not be required under Article 4.3 to include any of
            the Holders' securities in such underwriting unless they accept the
            terms of the underwriting as agreed upon between the Company and the
            underwriters selected by it (or by other persons entitled to select
            the underwriters), and then only in such quantity as the
            underwriters determine in their sole discretion will not jeopardize
            the success of the offering by the Company. If the total amount of
            securities, including Registrable Securities, requested by
            stockholders to be included in such offering


                                     - 10 -



            exceeds the amount of securities sold other than by the Company that
            the underwriters determine in their sole discretion is compatible
            with the success of the offering, then the Company shall be required
            to include in the offering only that number of such securities,
            including Registrable Securities, which the underwriters determine
            in their sole discretion will not jeopardize the success of the
            offering (the securities so included to be apportioned pro rata
            among the selling stockholders according to the total amount of
            securities entitled to be included therein owned by each selling
            stockholder or in such other proportions as shall mutually be agreed
            to by such selling stockholders). For purposes of the preceding
            parenthetical concerning apportionment, for any selling stockholder
            that is a holder of Registrable Securities and that 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 persons shall be deemed to be a single "selling
            stockholder", and any pro-rata reduction with respect to such
            "selling stockholder" shall be based upon the aggregate amount of
            shares carrying registration rights owned by all entities and
            individuals included in such "selling stockholder", as defined in
            this sentence.

      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 Article IV.

      9     Indemnification. In the event any Registrable Securities are
            included in a registration statement under this Article IV:

            (a)   To the extent permitted by law, the Company will indemnify and
                  hold harmless each Holder, any underwriter (as defined in the
                  Act) for such Holder and each person, if any, who controls
                  such Holder or underwriter within the meaning of the Act or
                  the 1934 Act, against any losses, claims, damages, or
                  liabilities (joint or several) to which they may become
                  subject under the Act, or the 1934 Act, 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"): (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 of the
                  Act, the 1934 Act, or any rule or regulation promulgated under
                  the Act, or the 1934 Act, and the Company will pay to each
                  such Holder, underwriter or controlling person, as incurred,
                  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


                                     - 11 -



                  contained in this Article 4.9(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 famished expressly for use in connection with such
                  registration by any such Holder, underwriter or controlling
                  person.

            (b)   To the extent permitted by law, each selling Holder will
                  indemnify and hold harmless the Company, each of its
                  directors, each of its officers who has signed the
                  registration statement, each person, if any, who controls the
                  Company within the meaning of the Act, any underwriter, any
                  other Holder selling securities in such registration statement
                  and any controlling person of any such underwriter or other
                  Holder, against any losses, claims, damages, or liabilities
                  (joint or several) to which any of the foregoing persons may
                  become subject, under the Act, or the 1934 Act, 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 expressly for use
                  in connection with such registration; and each such Holder
                  will pay, as incurred, any legal or other expenses reasonably
                  incurred by any person intended to be indemnified pursuant to
                  this Article 4.9(b), in connection with investigating or
                  defending any such loss, claim, damage, liability, or action;
                  provided, however, that the indemnity agreement contained in
                  this Article 4.9(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, that, in no event shall any indemnity under this
                  Article 4.9(b) exceed the gross proceeds from the offering
                  received by such Holder.

            (c)   Promptly after receipt by an indemnified party under this
                  Article 4.9 of notice of the commencement of any action
                  (including any governmental action), such indemnified party
                  shall, if a claim in respect thereof is to be made against any
                  indemnifying party under this Article 4.9, 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
                  notified, to assume the defense thereof with counsel selected
                  by the indemnifying party and approved by the indemnified
                  party (whose approval shall not be unreasonably withheld);
                  provided, however, that an indemnified party (together with
                  all other indemnified parties which may be represented without
                  conflict by one counsel) shall have the right to retain one
                  separate counsel, with the fees and expenses to be paid


                                     - 12 -



                  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 potential
                  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 prejudicial to its ability to defend such action,
                  shall relieve such indemnifying party of any liability to the
                  indemnified party under this Article 4.9, but the omission so
                  to 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 Article 4.9.

            (d)   If the indemnification provided for in this Article 4.9 is
                  held by a court of competent jurisdiction to be unavailable to
                  an indemnified party with respect to any loss, liability,
                  claim, damage, or expense referred to therein, then the
                  indemnifying party, in lieu of indemnifying such indemnified
                  party hereunder, shall contribute to the amount paid or
                  payable by such indemnified party as a result of such loss,
                  liability, claim, damage, or expense 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 statements or omissions that
                  resulted in such loss, liability, claim, damage, or expense as
                  well as any other relevant equitable considerations. The
                  relative fault of the indemnifying party and of the
                  indemnified party shall be determined 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.

            (e)   Notwithstanding the foregoing, to the extent that the
                  provisions on indemnification and contribution contained in
                  the underwriting agreement entered into in connection with the
                  underwritten public offering are in conflict with the
                  foregoing provisions, the provisions in the underwriting
                  agreement shall control.

            (f)   The obligations of the Company and Holders under this Article
                  4.9 shall survive the completion of any offering of
                  Registrable Securities in a registration statement under this
                  Article IV, and otherwise.

      10    Reports Under Securities Exchange Act of 1934. With a view to making
            available to the Holders the benefits of Rule 144 promulgated under
            the Act and any other rule or regulation of the SEC that may at any
            time permit a Holder to sell securities of the Company to the public
            without registration or pursuant to a registration on Form S-3, the
            Company agrees to:


                                     - 13 -



            (a)   make and keep public information available, as those terms are
                  understood and defined in SEC Rule 144, at all times after
                  ninety (90) days after the effective date of the registration
                  statement filed in connection with an IPO by the Company;

            (b)   file with the SEC in a timely manner all reports and other
                  documents required of the Company under the Act and the 1934
                  Act; and

            (c)   furnish to any Holder, so long as the Holder owns any
                  Registrable Securities, forthwith upon request (i) a copy of
                  the most recent annual or quarterly report of the Company and
                  such other reports and documents so filed by the Company, and
                  (ii) such other information as may be reasonably requested in
                  availing any Holder of any rule or regulation of the SEC which
                  permits the selling of any such securities without
                  registration or pursuant to such form.

      11    Lock-Up Provision. In connection with the IPO, the Holder hereby
            agrees to be subject to a lock-up for a period of one hundred eighty
            (180) days following the IPO or such longer period as may be
            required by the underwriter or underwriters of such IPO. In
            connection with any subsequent public offering of the Company's
            securities, the Holder hereby agrees to be subject to a lock-up for
            a period of sixty (60) days or such longer period following such
            public offering as required by the underwriter or underwriters of
            such public offering. During such periods, the Holder agrees not to
            directly or indirectly sell, offer to sell, contract to sell,
            including, without limitation, "short" or "short against the box"
            (as those terms are generally understood), grant any option to
            purchase or otherwise transfer or dispose of (other than to donees
            who agree to be similarly bound) any securities of the Company held
            by it at any time during such period. This Article 4.11 shall be
            binding upon any transferee of the Securities.

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

            Notwithstanding the foregoing, the obligation described in this
            Article 4.11 shall not apply to a registration relating solely to
            employee benefit plans on Form S-1 or Form S-8 or similar forms
            which may be promulgated in the future, or a registration relating
            solely to a Commission Rule 145 transaction on Form S-4 or similar
            forms which may be promulgated in the future.

      12    Termination of Registration Rights. In addition, the right of any
            Holder to request inclusion in any registration pursuant to Article
            4.3 shall terminate if all shares of Registrable Securities held by
            such Holder may immediately be sold under Rule 144 or Rule 701
            during any 90-day period; provided, however, that the provisions of
            this Article 4.12 shall not apply to any Holder who owns more than
            two percent


                                     - 14 -



            (2%) of the Company's outstanding stock until such time as such
            Holder owns less than two percent (2%) of the outstanding stock of
            the Company.

      2     This Agreement shall not be changed, modified or amended except by a
            writing signed by the parties to be charged, and this Agreement may
            not be discharged except by performance in accordance with its terms
            or by a writing signed by the party to be charged.

      3     This Agreement shall be binding upon and inure to the benefit of the
            parties hereto and to their respective heirs, legal representatives,
            successors and assigns. This Agreement sets forth the entire
            agreement and understanding between the parties as to the subject
            matter hereof and merges and supersedes all prior discussions,
            agreements and understandings of any and every nature among them.

      4     Upon the execution and delivery of this Agreement by the Subscriber,
            this Agreement shall become a binding obligation of the Subscriber

            reject or decrease any subscription, enter into the same agreements
            with other subscribers and to add and/or delete other Persons as
            subscribers.

            TERMS AND PROVISIONS HEREOF SHALL BE CONSTRUED IN ACCORDANCE WITH
            AND GOVERNED BY THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO
            PRINCIPLES OF CONFLICTS OF LAW.

      6     In order to discourage frivolous claims, the parties agree that
            unless a claimant in any proceeding arising out of this Agreement
            succeeds in establishing his claim and recovering a judgment against
            another party (regardless of whether such claimant succeeds against
            one of the other parties to the action), then the other party shall
            be entitled to recover from such claimant all of its/their
            reasonable


                                     - 15 -



            legal costs and expenses relating to such proceeding and/or incurred
            in preparation therefor.

      7     The holding of any provision of this Agreement to be invalid or
            unenforceable by a court of competent jurisdiction shall not affect
            any other provision of this Agreement, which shall remain in full
            force and effect. If any provision of this Agreement shall be
            declared by a court of competent jurisdiction to be invalid, illegal
            or incapable of being enforced in whole or in part, such provision
            shall be interpreted so as to remain enforceable to the maximum
            extent permissible consistent with applicable law and the remaining
            conditions and provisions or portions thereof shall nevertheless
            remain in full force and effect and enforceable to the extent they
            are valid, legal and enforceable, and no provisions shall be deemed
            dependent upon any other covenant or provision unless so expressed
            herein.

      8     It is agreed that a waiver by either party of a breach of any
            provision of this Agreement shall not operate, or be construed, as a
            waiver of any subsequent breach by that same party.

      9     The parties agree to execute and deliver all such further documents,
            agreements and instruments and take such other and further action as
            may be necessary or appropriate to carry out the purposes and intent
            of this Agreement.

      10    This Agreement may be executed in two or more counterparts each of
            which shall be deemed an original, but all of which shall together
            constitute one and the same instrument.

      11    (a) The Subscriber agrees not to issue any public statement with
            respect to the Subscriber's investment or proposed investment in the
            Company or the terms of any agreement or covenant between it and the

            applicable order, rule or regulation.

            (b) The Company agrees not to disclose the names, addresses or any
            other information about the Subscribers, except as required by law;
            provided, that the Company may use the name (but not the address) of
            the Subscriber in registration materials filed with the SEC.

      12    The Subscriber represents and warrants that it has not engaged,
            consented to or authorized any broker, finder or intermediary to act
            on its behalf, directly or indirectly, as a broker, finder or
            intermediary in connection with the transactions contemplated by
            this Agreement. The Subscriber hereby agrees to indemnify and hold
            harmless the Company from and against all fees, commissions or other
            payments owing to any such person or firm acting on behalf of the
            Subscriber hereunder.

      13    Nothing in this Agreement shall create or be deemed to create any
            rights in any Person not a party to this Agreement, except for the
            holders of Registrable Securities.

VI    CONFIDENTIAL INVESTOR QUESTIONNAIRE

            6.1 The Subscriber represents and warrants that the Subscriber comes
within one category marked below, and that for any category marked, the
Subscriber has truthfully set forth, where applicable, the factual basis or
reason the Subscriber comes within that category. ALL INFORMATION IN RESPONSE TO
THIS Article WILL BE KEPT STRICTLY CONFIDENTIAL. The Subscriber agrees to
furnish any additional information which the Company deems necessary in order to
verify the answers set forth below.

Category A | |    The Subscriber is an individual (not a partnership,
                  corporation, etc.) whose individual net worth, or joint net
                  worth with his or her spouse, presently exceeds $1,000,000.

                        Explanation. In calculating net worth you may include

                        your principal residence, cash, short-term investments,
                        stock and securities. Equity in personal property and
                        real estate should be based on the fair market value of
                        such property less debt secured by such property.

Category B | |    The Subscriber is an individual (not a partnership,
                  corporation, etc.) who had an income in excess of $200,000 in
                  each of the two most recent years, or joint income with his or
                  her spouse in excess of $300,000 in each of those years (in
                  each case including foreign income, tax exempt income and full
                  amount of capital gains and losses but excluding any income of
                  other family members and any unrealized capital appreciation)
                  and has a reasonable expectation of reaching the same income
                  level in the current year.

Category C |_|    The Subscriber is a director or executive officer of the
                  Company which is issuing and selling the Preferred Stock.

                  investment company ("SBIC"); or employee benefit plan within

                  decisions made solely by persons that are accredited
                  investors.
