                                                                       ---------

PURCHASER. Purchaser hereby represents, warrants and acknowledges to the
Company, and the Company may rely on the same in completing the sale of the
Purchased Shares and the other transactions herein contemplated, as of the
Subscription Date, as follows:


   2



                      5.01  VALIDITY. This Subscription Agreement constitutes
           the legally valid and binding obligation of Purchaser enforceable
           against Purchaser in accordance with its terms.

                      5.02  STATE OF RESIDENCE. The state of residence of
           Purchaser is, and shall be at the time of delivery and acceptance of
           the Purchased Shares, the State of New Jersey.

                      5.03  ACCESS. Purchaser has had access to all documents,
           records and books pertaining to the Company at the office of the
           Company upon reasonable notice to the Company and has had the
           opportunity to ask questions of and receive answers from the
           officers of the Company concerning the operations of the Company and
           the purchase of the Purchased Shares. Prior to the date hereof,
           Purchaser has received copies of (i) the Company's Form 10-K for the
           year ended December 31, 1996; (ii) the Company's Forms 10-Q for the
           quarters ended March 31, 1997 and June 30, 1997, respectively; (iii)
           the Company's Notice of Annual Meeting of Stockholders and Proxy
           Statement with respect to the annual meeting held on May 9, 1997;
           and (iv) the Company's Annual Report for the year ended December 31,
           1997 (collectively, the "Disclosed Documents").

                      5.04  NO REVIEW. Purchaser is aware that no federal or
           state agency has made any finding or determination as to the
           fairness for public or private investment, nor any recommendation or
           endorsement, of the Purchased Shares as an investment.

                      5.05  SPECULATIVE NATURE. Purchaser recognizes the
           speculative nature of an investment in the Purchased Shares.

                      5.06  HOLDING OF PURCHASED SHARES. As a purchaser of the
           Purchased Shares, Purchaser must bear the economic risk of his
           investment in the Purchased Shares for an indefinite period of time
           because the Purchased Shares have not been registered under the
           Securities Act of 1933, as amended (the "1933 Act"), in reliance
           upon an exemption from such registration requirements set forth in
           Rule 506 of Regulation D promulgated under the 1933 Act ("Regulation
           D") and, therefore, cannot be sold unless they are subsequently
           registered under the 1933 Act or an exemption from such registration
           is available; the Company shall make a notation in its transfer
           records regarding said restrictions on transfer of the Purchased
           Shares; and the Purchased Shares shall not be sold without
           registration under the 1933 Act or exemption therefrom.

                      5.07  FINANCIAL KNOWLEDGE AND EXPERIENCE. Purchaser has
           knowledge and experience in financial and business matters so as to
           be capable of evaluating the merits and risks of an investment in
           the Purchased Shares; is not utilizing any other person to be his
           "Purchaser Representative" (as defined in Regulation D) in
           connection with evaluating such merits and risks; and offers as
           evidence of his knowledge and experience in these matters the
           representations and information set forth in this Subscription
           Agreement.

                      5.08  ECONOMIC RISK. Purchaser is willing and able to bear
           the economic risk of an investment in the Purchased Shares (in
           making this representation, consideration has been given to whether
           Purchaser can afford to


   3



           hold the Purchased Shares for an indefinite period of time and
           whether, at this time, Purchaser can afford a complete loss of his
           investment).

                      5.09  ACCREDITED INVESTOR. Purchaser is an "accredited
           investor" as defined in Rule 501 of Regulation D (an "Accredited
           Investor"). In addition to certain institutional investors and
           fiduciaries, an Accredited Investor in the Company includes any
           person or entity that falls within any one of the following
           categories:

                                (a)  any natural person whose individual net
                      worth, or joint net worth with such person's spouse,
                      exceeds $1,000,000.00;

                                (b)  any natural person who had an individual
                      income in excess of $200,000.00 in each of the two most
                      recent tax years or joint income with such person's
                      spouse in excess of $300,000.00 in each of those years
                      and who reasonably expects to reach the same income level
                      in the current year;

                                (c)  any corporation, business trust or
                      partnership not formed for the specific purpose of
                      acquiring the Shares, with total assets in excess of
                      $5,000,000.00;

                                (d)  any entity in which all of the equity

                                (e)  any trust, with total assets in excess of
                      $5,000,000.00, not formed for the specific purpose of
                      acquiring the Shares, whose purchase is directed by a
                      "Sophisticated Person" (as described in Rule 506 of
                      Regulation D);

                                (f)  any employee benefit plan within the
                      meaning of the Employee Retirement Income Security Act of
                      1974 if the investment decision is made by a plan
                      fiduciary, as defined in Section 3(21) of such Act, which
                      is either a bank, savings and loan association, insurance
                      company or registered investment adviser, or if the
                      employee benefit plan has total assets in excess of
                      $5,000,000.00 or, if a self-directed plan, with
                      investment decisions made solely by persons who are
                      Accredited Investors; or

                                (g)  any director or executive officer of the
                      Company.

                      5.10  REGISTRATION OF PURCHASED SHARES. Purchaser
           understands and acknowledges that no aspect of the transactions
           contemplated in this Subscription Agreement has been, prior to the
           date of this Subscription Agreement, or will be, prior to the date
           of delivery and acceptance of the Purchased Shares, registered with
           or reviewed by the Securities and Exchange Commission under the 1933
           Act or with or by any state securities law administrator, and no
           federal or state securities law administrator has approved any
           disclosure or other material concerning the Company or the Purchased
           Shares or made any recommendation with respect thereto. Purchaser
           also understands and acknowledges that the Company has not granted
           Purchaser any rights whatsoever with respect to the


   4



           future registration of any Purchased Shares with any federal or
           state securities administrator or authority, including, but not
           limited to, any piggyback registration rights whereby the Purchased
           Shares would be registered in conjunction with the registration by
           the Company of any other of its issued securities.

                      5.11  COMMITMENTS. Purchaser's overall commitment to
           investments which are not readily marketable is not disproportionate
           to his net worth.

                      5.12  LIQUIDITY. Purchaser has adequate means of providing
           for his current needs and personal contingencies and has no need for
           liquidity in his investment in the Purchased Shares.

                      5.13  OBJECTIVE. The objectives of the Company are
           compatible with Purchaser's investment goals.

                      5.14  INVESTMENT. Purchaser is purchasing the Purchased
           Shares for the Purchaser's own account, as principal, for investment
           and not with a view to the resale or distribution of all or any part
           of the Purchased Shares.

                      5.15  ADVISOR. Purchaser has been advised by the Company
           that he should consult his own legal counsel, accountant or business
           advisor as to the legal, tax and other matters concerning his
           purchase of the Purchased Shares and his execution of this
           Subscription Agreement.

                      5.16  NO FINANCIAL PROJECTIONS. The Company has neither
           delivered nor disclosed to Purchaser any financial projections
           relating to the Company.

                      5.17  NO OTHER COMPANY MATERIALS. Purchaser acknowledges
           that the Company has made no oral or written representations or
           warranties to the Purchaser, either directly or indirectly, through
           its officers, directors, employees or agents, with respect to the
           Company or the Purchased Shares, other than those representations
           and warranties included herein. Purchaser further acknowledges that
           he has not relied on any disclosures of the Company, its directors,
           employees or agents, other than such disclosures as are set forth in
           the Disclosed Documents.

                    6. INDEMNIFICATION. Purchaser acknowledges his
understanding of the meaning and legal consequences of all the representations,
warranties and agreements contained in this Subscription Agreement and
Purchaser hereby agrees to indemnify and hold harmless the Company, its agents
and affiliates, successors and assigns from and against any and all loss,
damage, or liability arising out of, connected with or any way related to a
breach of any representation or warranty of Purchaser contained in this
Subscription Agreement.
