As Representatives of the several Underwriters
c/o FleetBoston Robertson Stephens Inc.
555 California Street, Suite 2600

Ladies and Gentlemen:

                  INTRODUCTORY. YOUcentric, Inc., a North Carolina corporation
(the "Company"), proposes to issue and sell to the several underwriters named in
Schedule A (the "Underwriters") an aggregate of [5,000,000] shares (the "Firm
Shares") of its Common Stock, no par value per share (the "Common Shares"). In
addition, the Company has granted to the Underwriters an option to purchase up
to an additional [750,000] Common Shares (the "Option Shares") as provided in
Section 2. The Firm Shares and, if and to the extent such option is exercised,
the Option Shares are collectively called the "Shares". FleetBoston Robertson
Stephens Inc. ("Robertson Stephens"), Dain Rauscher Incorporated, U.S. Bancorp
Piper Jaffray Inc. and Legg Mason Wood Walker, Inc. have agreed to act as
representatives of the several Underwriters (in such capacity, the
"Representatives") in connection with the offering and sale of the Shares.

                  As a part of this offering contemplated by this Agreement,
[Robertson Stephens] has agreed to reserve out of the Shares set forth opposite
its name on Schedule A to this Agreement, up to [250,000] Shares, for sale to
the Company's employees, officers, and directors and other parties associated
with the Company (collectively,"Participants"), as set forth in the Prospectus
under the heading "Underwriting" (the "Directed Share Program"). The Shares to
be sold by Robertson Stephens pursuant to the Directed Share Program (the
"Directed Shares") will be sold by Robertson Stephens pursuant to this Agreement
at the public offering price. Any Directed Shares not orally confirmed for
purchase by any Participants as of 7:00 a.m. California time on the first day
trading of the Shares commences will be offered to the public by Robertson
Stephens as set forth in the Prospectus.

                  The Company has prepared and filed with the Securities and
Exchange Commission (the "Commission") a registration statement on Form S-1
(Commission File No. 333-35104), which contains a form of prospectus, subject to
completion, to be used in connection with the public offering and sale of the
Shares. Each such prospectus, subject to completion, used in connection with
such public offering is called a "preliminary prospectus". Such registration
statement, as amended, including the financial statements, exhibits and
schedules thereto, in the form in which it was declared effective by the
Commission under the Securities Act of 1933 and the rules and regulations
promulgated thereunder (collectively, the "Securities Act"), including any
information deemed to be a part thereof at the time of


<PAGE>   2

effectiveness pursuant to Rule 430A under the Securities Act, is called the
"Registration Statement". Any registration statement filed by the Company
pursuant to Rule 462(b) under the Securities Act is called the "Rule 462(b)
Registration Statement", and from and after the date and time of filing of the
Rule 462(b) Registration Statement the term "Registration Statement" shall
include the Rule 462(b) Registration Statement. Such prospectus, in the form
first used by the Underwriters to confirm sales of the Shares, is called the
"Prospectus". All references in this Agreement to the Registration Statement,
the Rule 462(b) Registration Statement, a preliminary prospectus, the Prospectus
or any amendments or supplements to any of the foregoing, shall include any copy
thereof filed with the Commission pursuant to its Electronic Data Gathering,
Analysis and Retrieval System ("EDGAR").

                  The Company hereby confirms its agreements with the
Underwriters as follows:

         SECTION 1.        REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

         A.       REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company
hereby represents, warrants and covenants to each Underwriter as follows:

         (a)      Compliance with Registration Requirements. The Registration
Statement and any Rule 462(b) Registration Statement have been declared
effective by the Commission under the Securities Act. The Company has complied
to the Commission's satisfaction with all requests of the Commission for
additional or supplemental information. No stop order suspending the
effectiveness of the Registration Statement or any Rule 462(b) Registration
Statement is in effect and no proceedings for such purpose have been instituted
or are pending or, to the best knowledge of the Company, are contemplated or
threatened by the Commission.

                  Each preliminary prospectus and the Prospectus when filed
complied in all material respects with the Securities Act and, if filed by
electronic transmission pursuant to EDGAR (except as may be permitted by
Regulation S-T under the Securities Act), was identical to the copy thereof
delivered to the Underwriters for use in connection with the offer and sale of
the Shares. Each of the Registration Statement, any Rule 462(b) Registration
Statement and any post-effective amendment thereto, at the time it became
effective and at all subsequent times, complied and will comply in all material
respects with the Securities Act and did not and will not contain any untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading. Each
preliminary prospectus, as of its date, and the Prospectus, as amended or
supplemented, as of its date and at all subsequent times through the 30th day
after the date hereof, did not and will not contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in the light of the circumstances under which they were
made, not misleading. The representations and warranties set forth in the two
immediately preceding sentences do not apply to statements in or omissions from
the Registration Statement, any Rule 462(b) Registration Statement, or any
post-effective amendment thereto, or the Prospectus, or any amendments or
supplements thereto, made in reliance upon and in conformity with information
relating to any Underwriter furnished to the Company in writing by the
Representatives expressly for use therein. There are no contracts or other
documents required to be described in the Prospectus or to be filed as exhibits
to the Registration Statement which have not been described or filed as
required.

         (b)      Offering Materials Furnished to Underwriters. The Company has
delivered to the Representatives four complete conformed copy of the
Registration Statement and of each consent and certificate of experts filed as a
part thereof, and conformed copies of the


                                       2
<PAGE>   3

Registration Statement (without exhibits) and preliminary prospectuses and the
Prospectus, as amended or supplemented, in such quantities and at such places as
the Representatives have reasonably requested for each of the Underwriters.

         (c)      Distribution of Offering Material By the Company. The Company
has not distributed and will not distribute, prior to the later of the Second
Closing Date (as defined below) and the completion of the Underwriters'
distribution of the Shares, any offering material in connection with the
offering and sale of the Shares other than a preliminary prospectus, the
Prospectus or the Registration Statement.

         (d)      The Underwriting Agreement. This Agreement has been duly
authorized, executed and delivered by, and is a valid and binding agreement of,
the Company, enforceable in accordance with its terms, except as rights to
indemnification hereunder may be limited by applicable law and except as the
enforcement hereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other similar laws relating to or affecting the rights and
remedies of creditors or by general equitable principles.

         (e)      Authorization of the Shares. The Shares to be purchased by the
Underwriters from the Company have been duly authorized for issuance and sale
pursuant to this Agreement and, when issued and delivered by the Company
pursuant to this Agreement, will be validly issued, fully paid and
nonassessable.

         (f)      No Applicable Registration or Other Similar Rights. There are
no persons with registration or other similar rights to have any equity or debt
securities registered for sale under the Registration Statement or included in
the offering contemplated by this Agreement, except for such rights as have been
duly waived.

         (g)      No Material Adverse Change. Subsequent to the respective dates
as of which information is given in the Prospectus: (i) there has been no
material adverse change, or any development that could reasonably be expected to
result in a material adverse change, in the condition, financial or otherwise,
or in the earnings, business, operations or prospects, whether or not arising
from transactions in the ordinary course of business, of the Company (any such
change or effect, where the context so requires, is called a "Material Adverse
Change" or a "Material Adverse Effect"); (ii) the Company has not incurred any
material liability or obligation, indirect, direct or contingent, not in the
ordinary course of business nor entered into any material transaction or
agreement not in the ordinary course of business; and (iii) there has been no
dividend or distribution of any kind declared, paid or made by the Company on
any class of capital stock or repurchase or redemption by the Company of any
class of capital stock.

         (h)      Independent Accountants. Deloitte & Touche LLP, who have
expressed their opinion with respect to the financial statements (which term as
used in this Agreement includes the related notes thereto) filed with the
Commission as a part of the Registration Statement and included in the
Prospectus, are independent public or certified public accountants as required
by the Securities Act.

         (i)      Preparation of the Financial Statements. The financial
statements filed with the Commission as a part of the Registration Statement and
included in the Prospectus present fairly the financial position of the Company
as of and at the dates indicated and the results of their operations and cash
flows for the periods specified. Such financial statements have been prepared in
conformity with generally accepted accounting principles applied on a consistent
basis throughout the periods involved, except as may be expressly stated in the
related notes


                                       3
<PAGE>   4

thereto. No other financial statements or supporting schedules are required to
be included in the Registration Statement. The financial data set forth in the
Prospectus under the captions "Prospectus Summary--Summary Financial Data",
"Selected Financial Data" and "Capitalization" fairly present the information
set forth therein on a basis consistent with that of the audited financial
statements contained in the Registration Statement.

         (j)      Company's Accounting System. The Company maintains a system of
accounting controls sufficient to provide reasonable assurances that (i)
transactions are executed in accordance with management's general or specific
authorization; (ii) transactions are recorded as necessary to permit preparation
of financial statements in conformity with generally accepted accounting
principles and to maintain accountability for assets; (iii) access to assets is
permitted only in accordance with management's general or specific
authorization; and (iv) the recorded accountability for assets is compared with
existing assets at reasonable intervals and appropriate action is taken with
respect to any differences.

         (k)      Subsidiaries of the Company. The Company has no subsidiaries
and does not own or control, directly or indirectly, any corporation,
association or other entity.

         (l)      Incorporation and Good Standing of the Company. The Company
has been duly organized and is validly existing as a corporation, in good
standing under the laws of the jurisdiction in which it is organized with full
corporate power and authority to own its properties and conduct its business as
described in the prospectus, and is duly qualified to do business as a foreign
corporation and is in good standing under the laws of each jurisdiction which
requires such qualification.

         (m)      Capitalization and Other Capital Stock Matters. The
authorized, issued and outstanding capital stock of the Company is as set forth
in the Prospectus under the caption "Capitalization" (other than for subsequent
issuances, if any, pursuant to employee benefit plans described in the
Prospectus or upon exercise of outstanding options or warrants described in the
Prospectus). The Common Shares (including the Shares) conform in all material
respects to the description thereof contained in the Prospectus. All of the
issued and outstanding Common Shares have been duly authorized and validly
issued, are fully paid and nonassessable and have been issued in compliance with
federal and state securities laws. None of the outstanding Common Shares were
issued in violation of any preemptive rights, rights of first refusal or other
similar rights to subscribe for or purchase securities of the Company. There are
no authorized or outstanding options, warrants, preemptive rights, rights of
first refusal or other rights to purchase, or equity or debt securities
convertible into or exchangeable or exercisable for, any capital stock of the
Company other than those accurately described in the Prospectus. The description
of the Company's stock option, stock bonus and other stock plans or
arrangements, and the options or other rights granted thereunder, set forth in
the Prospectus accurately and fairly presents the information required to be
shown with respect to such plans, arrangements, options and rights.

         (n)      Nasdaq Listing. The Shares have been approved for listing on
The Nasdaq National Market, subject only to official notice of issuance.

         (o)      No Consents, Approvals or Authorizations Required. No consent,
approval, authorization, filing with or order of any court or governmental
agency or regulatory body is required in connection with the transactions
contemplated herein, except such as have been obtained or made under the
Securities Act and such as may be required (i) under the blue sky laws of any
jurisdiction in connection with the purchase and distribution of the Shares by
the


                                       4
<PAGE>   5

Underwriters in the manner contemplated here and in the Prospectus, (ii) by
the National Association of Securities Dealers, Inc. and (iii) by the federal
and provincial laws of Canada.

         (p)      Non-Contravention of Existing Instruments Agreements. Neither
the issue and sale of the Shares nor the consummation of any other of the
transactions herein contemplated nor the fulfillment of the terms hereof will
conflict with, result in a breach or violation or imposition of any lien, charge
or encumbrance upon any property or assets of the Company pursuant to, (i) the
charter or by-laws of the Company, (ii) the terms of any indenture, contract,
lease, mortgage, deed of trust, note agreement, loan agreement or other
agreement, obligation, condition, covenant or instrument to which the Company is
a party or bound or to which its property is subject or (iii) any statute, law,
rule, regulation, judgment, order or decree applicable to the Company of any
court, regulatory body, administrative agency, governmental body, arbitrator or
other authority having jurisdiction over the Company or any of its properties.

         (q)      No Defaults or Violations. The Company is not in violation or
default of (i) any provision of its charter or by-laws, (ii) the terms of any
indenture, contract, lease, mortgage, deed of trust, note agreement, loan
agreement or other agreement, obligation, condition, covenant or instrument to
which it is a party or bound or to which its property is subject or (iii) any
statute, law, rule, regulation, judgment, order or decree of any court,
regulatory body, administrative agency, governmental body, arbitrator or other
authority having jurisdiction over the Company or any of its properties, except
any such violation or default which would not, singly or in the aggregate,
result in a Material Adverse Change except as otherwise disclosed in the
Prospectus.

         (r)      No Actions, Suits or Proceedings. No action, suit or
proceeding by or before any court or governmental agency, authority or body or
any arbitrator involving the Company or its property is pending or, to the best
knowledge of the Company, threatened that (i) could reasonably be expected to
have a Material Adverse Effect on the performance of this Agreement or the
consummation of any of the transactions contemplated hereby or (ii) could
reasonably be expected to result in a Material Adverse Effect.

         (s)      All Necessary Permits, Etc. The Company possesses such valid
and current certificates, authorizations or permits issued by the appropriate
state, federal or foreign regulatory agencies or bodies necessary to conduct its
business, and the Company has not received any notice of proceedings relating to
the revocation or modification of, or non-compliance with, any such certificate,
authorization or permit which, singly or in the aggregate, if the subject of an
unfavorable decision, ruling or finding, could result in a Material Adverse
Change.

         (t)      Title to Properties. The Company has good and marketable title
to all the properties and assets reflected as owned in the financial statements
referred to in Section 1(A)(i) above (or elsewhere in the Prospectus), in each
case free and clear of any security interests, mortgages, liens, encumbrances,
equities, claims and other defects, except such as do not materially and
adversely affect the value of such property and do not materially interfere with
the use made or proposed to be made of such property by the Company. The real
property, improvements, equipment and personal property held under lease by the
Company are held under valid and enforceable leases, with such exceptions as are
not material and do not materially interfere with the use made or proposed to be
made of such real property, improvements, equipment or personal property by the
Company.


                                       5
<PAGE>   6

         (u)      Tax Law Compliance. The Company has filed all necessary
federal, state and foreign income and franchise tax returns and has paid all
taxes required to be paid by it and, if due and payable, any related or similar
assessment, fine or penalty levied against it. The Company has made adequate
charges, accruals and reserves in the applicable financial statements referred
to in Section 1(A)(i) above in respect of all federal, state and foreign income
and franchise taxes for all periods as to which the tax liability of the Company
has not been finally determined. The Company is not aware of any tax deficiency
that has been or might be asserted or threatened against the Company that could
result in a Material Adverse Change.

         (v)      Intellectual Property Rights. The Company owns or possesses
adequate rights to use all patents, patent rights or licenses, inventions,
collaborative research agreements, trade secrets, know-how, trademarks, service
marks, trade names and copyrights which are necessary to conduct its businesses
as described in the Registration Statement and Prospectus; the expiration of any
patents, patent rights, trade secrets, trademarks, service marks, trade names or
copyrights would not result in a Material Adverse Change that is not otherwise
disclosed in the Prospectus; the Company has not received any notice of, and has
no knowledge of, any infringement of or conflict with asserted rights of the
Company by others with respect to any patent, patent rights, inventions, trade
secrets, know-how, trademarks, service marks, trade names or copyrights; and the
Company has not received any notice of, and has no knowledge of, any
infringement of or conflict with asserted rights of others with respect to any
patent, patent rights, inventions, trade secrets, know-how, trademarks, service
marks, trade names or copyrights which, singly or in the aggregate, if the
subject of an unfavorable decision, ruling or finding, might have a Material
Adverse Change. There is no claim being made against the Company regarding
patents, patent rights or licenses, inventions, collaborative research, trade
secrets, know-how, trademarks, service marks, trade names or copyrights. The
Company does not in the conduct of its business as now or proposed to be
conducted as described in the Prospectus infringe or conflict with any right or
patent of any third party, or any discovery, invention, product or process which
is the subject of a patent application filed by any third party, known to the
Company, which such infringement or conflict is reasonably likely to result in a
Material Adverse Change.

         (w)      Y2K. There are no Y2K issues related to the Company that (i)
are of a character required to be described or referred to in the Registration
Statement or Prospectus by the Securities Act which have not been accurately
described in the Registration Statement or Prospectus, or (ii) might reasonably
be expected to result in any Material Adverse Change or that might materially
affect their properties, assets or rights.

         (x)      No Transfer Taxes or Other Fees. There are no transfer taxes
or other similar fees or charges under Federal law or the laws of any state, or
any political subdivision thereof, required to be paid in connection with the
execution and delivery of this Agreement or the issuance and sale by the Company
of the Shares.

         (y)      Company Not an "Investment Company". The Company has been
advised of the rules and requirements under the Investment Company Act of 1940,
as amended (the "Investment Company Act"). The Company is not, and after receipt
of payment for the Shares will not be, an "investment company" or an entity
"controlled" by an "investment company" within the meaning of the Investment
Company Act and will conduct its business in a manner so that it will not become
subject to the Investment Company Act.

         (z) Insurance. The Company is insured by recognized, financially sound
and reputable institutions with policies in such amounts and with such
deductibles and covering such


                                       6
<PAGE>   7

risks as are generally deemed adequate and customary for their businesses
including, but not limited to, policies covering real and personal property
owned or leased by the Company against theft, damage, destruction, acts of
vandalism and earthquakes, general liability and Directors and Officers
liability. The Company has no reason to believe that it will not be able (i) to
renew its existing insurance coverage as and when such policies expire or (ii)
to obtain comparable coverage from similar institutions as may be necessary or
appropriate to conduct its business as now conducted and at a cost that would
not result in a Material Adverse Change. The Company has not been denied any
insurance coverage which it has sought or for which it has applied.

         (aa)     Labor Matters. To the best of the Company's knowledge, no
labor disturbance by the employees of the Company exists or is imminent; and the
Company is not aware of any existing or imminent labor disturbance by the
employees of any of its principal suppliers, distribution partners, licensors,
subcontractors, authorized dealers or parties from whom the Company licenses
software or other products or information that might be expected to result in a
Material Adverse Change.

         (bb)     No Price Stabilization or Manipulation. The Company has not
taken and will not take, directly or indirectly, any action designed to or that
might be reasonably expected to cause or result in stabilization or manipulation
of the price of the Common Stock to facilitate the sale or resale of the Shares.

         (cc)     Lock-Up Agreements. Each officer and director of the company
and each beneficial owner of any of the outstanding issued share capital of the
Company [OR OTHER INSTRUMENT THAT IS CONVERTIBLE INTO THE COMPANY'S COMMON
STOCK?] has signed an agreement substantially in the form attached hereto as
Exhibit A (the "Lock-up Agreements"). The Company has provided to counsel for
the Underwriters a complete and accurate list of all securityholders of the
Company and the number and type of securities held by each securityholder. The
Company has provided to counsel for the Underwriters true, accurate and complete
copies of all of the Lock-up Agreements presently in effect or effected hereby.
The Company hereby represents and warrants that it will not release any of its
officers, directors or other stockholders from any Lock-up Agreements currently
existing or hereafter effected without the prior written consent of Robertson
Stephens.

         (dd)     Related Party Transactions. There are no business
relationships or related-party transactions involving the Company or any other
person required to be described in the Prospectus which have not been described
as required.

         (ee)     ERISA Compliance. The Company and any "employee benefit plan"
(as defined under the Employee Retirement Income Security Act of 1974, as
amended, and the regulations and published interpretations thereunder
(collectively, "ERISA")) established or maintained by the Company are in
compliance in all material respects with ERISA. No "reportable event" (as
defined under ERISA) has occurred or is reasonably expected to occur with
respect to any "employee benefit plan" established or maintained by the Company.
No "employee benefit plan" established or maintained by the Company, if such
"employee benefit plan" were terminated, would have any "amount of unfounded
benefit liabilities" (as defined under ERISA). The Company has not incurred and
does not reasonably expect to incur any liability under (i) Title IV of ERISA
with respect to termination of, or withdrawal from, any "employee benefit plan"
or (ii) Sections 412, 4971, 4975 or 4980B of the Internal Revenue Code of 1986,
as amended (the "Code"). Each "employee benefit plan" established or maintained
by the Company that is intended to be qualified under Section 401(a)


                                       7
<PAGE>   8
of the Code is so qualified and nothing has occurred, whether by action or
failure to act, which would cause the loss of such qualification.

         (ff)     Consents Required in Connection with the Directed Share
Program. No consent, approval, authorization or order of, or qualification with,
any governmental body or agency, other than those obtained, is required in
connection with the offering of the Directed Shares in any jurisdiction where
the Directed Shares are being offered.

         (gg)     No Improper Influence in Connection with the Directed Share
Program. The Company has not offered, or caused Robertson Stephens to offer,
Shares to any person pursuant to the Directed Share Program with the specific
intent to unlawfully influence (i) a customer or supplier of the Company to
alter the customer's or supplier's level or type of business with the Company or
(ii) a trade journalist or publication to write or publish favorable information
about the Company or its products.

         Any certificate signed by an officer of the Company and delivered to
the Representatives or to counsel for the Underwriters shall be deemed to be a
representation and warranty by the Company to each Underwriter as to the matters
set forth therein.

         SECTION 2.        PURCHASE, SALE AND DELIVERY OF THE SHARES.

         (a)      The Firm Shares. The Company agrees to issue and sell to the
several Underwriters the Firm Shares upon the terms herein set forth. On the
basis of the representations, warranties and agreements herein contained, and
upon the terms but subject to the conditions herein set forth, the Underwriters
agree, severally and not jointly, to purchase from the Company the respective
number of Firm Shares set forth opposite their names on Schedule A. The purchase
price per Firm Share to be paid by the several Underwriters to the Company shall
be $[15.00] per share.

         (b)      The First Closing Date. Delivery of the Firm Shares to be
purchased by the Underwriters and payment therefor shall be made by the Company
and the Representatives at 6:00 a.m. San Francisco time, at the offices of
Kilpatrick Stockton LLP, 3500 One First Union Center, 301 S. College Street,
Suite 3500, Charlotte, North Carolina 28202 (or at such other place as may be
agreed upon among the Representatives and the Company), (i) on the third (3rd)
full business day following the first day that Shares are traded, (ii) if this
Agreement is executed and delivered after 1:30 P.M., San Francisco time, the
fourth (4th) full business day following the day that this Agreement is executed
and delivered or (iii) at such other time and date not later that seven (7) full
business days following the first day that Shares are traded as the
Representatives and the Company may determine (or at such time and date to which
payment and delivery shall have been postponed pursuant to Section 8 hereof),
such time and date of payment and delivery being herein called the "Closing
Date;" provided, however, that if the Company has not made available to the
Representatives copies of the Prospectus within the time provided in Section
2(g) and 3(e) hereof, the Representatives may, in their sole discretion,
postpone the Closing Date until no later that two (2) full business days
following delivery of copies of the Prospectus to the Representatives.

         (c)      The Option Shares; the Second Closing Date. In addition, on
the basis of the representations, warranties and agreements herein contained,
and upon the terms but subject to the conditions herein set forth, the Company
hereby grants an option to the several Underwriters to purchase, severally and
not jointly, up to an aggregate of [750,000] Option Shares from the Company at
the purchase price per share to be paid by the Underwriters for the


                                       8
<PAGE>   9

Firm Shares. The option granted hereunder is for use by the Underwriters solely
in covering any over-allotments in connection with the sale and distribution of
the Firm Shares. The option granted hereunder may be exercised at any time upon
notice by the Representatives to the Company, which notice may be given at any
time within 30 days from the date of this Agreement. The time and date of
delivery of the Option Shares, if subsequent to the First Closing Date, is
called the "Second Closing Date" and shall be determined by the Representatives
and shall not be earlier than three nor later than five full business days after
delivery of such notice of exercise. If any Option Shares are to be purchased,
each Underwriter agrees, severally and not jointly, to purchase the number of
Option Shares (subject to such adjustments to eliminate fractional Shares as the
Representatives may determine) that bears the same proportion to the total
number of Option Shares to be purchased as the number of Firm Shares set forth
on Schedule A opposite the name of such Underwriter bears to the total number of
Firm Shares. The Representatives may cancel the option at any time prior to its
expiration by giving written notice of such cancellation to the Company.

         (d)      Public Offering of the Shares. The Representatives hereby
advise the Company that the Underwriters intend to offer for sale to the public,
as described in the Prospectus, their respective portions of the Shares as soon
after this Agreement has been executed and the Registration Statement has been
declared effective as the Representatives, in their sole judgment, have
determined is advisable and practicable.

         (e)      Payment for the Shares. Payment for the Shares shall be made
at the First Closing Date (and, if applicable, at the Second Closing Date) by
wire transfer in immediately available-funds to the order of the Company.

                  It is understood that the Representatives have been
authorized, for their own account and the accounts of the several Underwriters,
to accept delivery of and receipt for, and make payment of the purchase price
for, the Firm Shares and any Option Shares the Underwriters have agreed to
purchase. Robertson Stephens, individually and not as a Representative of the
Underwriters, may (but shall not be obligated to) make payment for any Shares to
be purchased by any Underwriter whose funds shall not have been received by the
Representatives by the First Closing Date or the Second Closing Date, as the
case may be, for the account of such Underwriter, but any such payment shall not
relieve such Underwriter from any of its obligations under this Agreement.

         (f)      Delivery of the Shares. The Company shall deliver, or cause to
be delivered, a credit representing the Firm Shares to an account or accounts at
The Depository Trust Company, as designated by the Representatives for the
accounts of the Representatives and the several Underwriters at the First
Closing Date, against the irrevocable release of a wire transfer of immediately
available funds for the amount of the purchase price therefor. The Company shall
also deliver, or cause to be delivered, a credit representing the Option Shares
the Underwriters have agreed to purchase at the First Closing Date (or the
Second Closing Date, as the case may be), to an account or accounts at The
Depository Trust Company as designated by the Representatives for the accounts
of the Representatives and the several Underwriters, against the irrevocable
release of a wire transfer of immediately available funds for the amount of the
purchase price therefor. Time shall be of the essence, and delivery at the time
and place specified in this Agreement is a further condition to the obligations
of the Underwriters.

         (g)      Delivery of Prospectus to the Underwriters. Not later than
12:00 noon on the second business day following the date the Shares are released
by the Underwriters for sale to



                                       9
<PAGE>   10

the public, the Company shall deliver or cause to be delivered copies of the
Prospectus in such quantities and at such places as the Representatives shall
request.

         SECTION 3.        COVENANTS OF THE COMPANY.

         A.       COVENANTS OF THE COMPANY. The Company further covenants and
agrees with each Underwriter as follows:

         (a)      Registration Statement Matters. The Company will (i) use its
best efforts to cause a registration statement on Form 8-A (the "Form 8-A
Registration Statement") as required by the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), to become effective simultaneously with the
Registration Statement, (ii) use its best efforts to cause the Registration
Statement to become effective or, if the procedure in Rule 430A of the
Securities Act is followed, to prepare and timely file with the Commission under
Rule 424(b) under the Securities Act a Prospectus in a form approved by the
Representatives containing information previously omitted at the time of
effectiveness of the Registration Statement in reliance on Rule 430A of the
Securities Act and (iii) not file any amendment to the Registration Statement or
supplement to the Prospectus of which the Representatives shall not previously
have been advised and furnished with a copy or to which the Representatives
shall have reasonably objected in writing or which is not in compliance with the
Securities Act. If the Company elects to rely on Rule 462(b) under the
Securities Act, the Company shall file a Rule 462(b) Registration Statement with
the Commission in compliance with Rule 462(b) under the Securities Act prior to
the time confirmations are sent or given, as specified by Rule 462(b)(2) under
the Securities Act, and shall pay the applicable fees in accordance with Rule
111 under the Securities Act.

         (b)      Securities Act Compliance. The Company will advise the
Representatives promptly (i) when the Registration Statement or any
post-effective amendment thereto shall have become effective, (ii) of receipt of
any comments from the Commission, (iii) of any request of the Commission for
amendment of the Registration Statement or for supplement to the Prospectus or
for any additional information and (iv) of the issuance by the Commission of any
stop order suspending the effectiveness of the Registration Statement or the use
of the Prospectus or of the institution of any proceedings for that purpose. The
Company will use its best efforts to prevent the issuance of any such stop order
preventing or suspending the use of the Prospectus and to obtain as soon as
possible the lifting thereof, if issued.

         (c)      Blue Sky Compliance. The Company will cooperate with the
Representatives and counsel for the Underwriters in endeavoring to qualify the
Shares for sale under the securities laws of such jurisdictions (both national
and foreign) as the Representatives may reasonably have designated in writing
and will make such applications, file such documents, and furnish such
information as may be reasonably required for that purpose, provided the Company
shall not be required to qualify as a foreign corporation or to file a general
consent to service of process in any jurisdiction where it is not now so
qualified or required to file such a consent. The Company will, from time to
time, prepare and file such statements, reports and other documents, as are or
may be required to continue such qualifications in effect for so long a period
as the Representatives may reasonably request for distribution of the Shares.

         (d)      Amendments and Supplements to the Prospectus and Other
Securities Act Matters. The Company will comply with the Securities Act and the
Exchange Act, and the rules and regulations of the Commission thereunder, so as
to permit the completion of the distribution of the Shares as contemplated in
this Agreement and the Prospectus. If during the period in which a prospectus is
required by law to be delivered by an Underwriter or dealer, any event


                                       10
<PAGE>   11

shall occur as a result of which, in the judgment of the Company or in the
reasonable opinion of the Representatives or counsel for the Underwriters, it
becomes necessary to amend or supplement the Prospectus in order to make the
statements therein, in the light of the circumstances existing at the time the
Prospectus is delivered to a purchaser, not misleading, or, if it is necessary
at any time to amend or supplement the Prospectus to comply with any law, the
Company promptly will prepare and file with the Commission, and furnish at its
own expense to the Underwriters and to dealers, an appropriate amendment to the
Registration Statement or supplement to the Prospectus so that the Prospectus as
so amended or supplemented will not, in the light of the circumstances when it
is so delivered, be misleading, or so that the Prospectus will comply with the
law.

         (e)      Copies of any Amendments and Supplements to the Prospectus.
The Company agrees to furnish the Representatives, without charge, during the
period beginning on the date hereof and ending on the later of the First Closing
Date or such date, as in the opinion of counsel for the Underwriters, the
Prospectus is no longer required by law to be delivered in connection with sales
by an Underwriter or dealer (the "Prospectus Delivery Period"), as many copies
of the Prospectus and any amendments and supplements thereto as the
Representatives may request.

         (f)      Insurance. The Company shall (i) obtain Directors and Officers
liability insurance in the minimum amount of $[10] million which shall apply to
the offering contemplated hereby and (ii) cause Robertson Stephens to be added
to such policy such that up to $[500,000] of its expenses pursuant to section
7(a) shall be paid directly by such insurer [and (iii) shall cause Robertson
Stephens to be added as an additional insured to such policy in respect of the
offering contemplated hereby.]

         (g)      Notice of Subsequent Events. If at any time during the ninety
(90) day period after the Registration Statement becomes effective, any rumor,
publication or event relating to or affecting the Company shall occur as a
result of which, in your opinion, the market price of the Company Shares has
been or is likely to be materially affected (regardless of whether such rumor,
publication or event necessitates a supplement to or amendment of the
Prospectus), the Company will, after written notice from you advising the
Company to the effect set forth above, forthwith prepare, consult with you
concerning the substance of and disseminate a press release or other public
statement, reasonably satisfactory to you, responding to or commenting on such
rumor, publication or event.

         (h)      Use of Proceeds. The Company shall apply the net proceeds from
the sale of the Shares sold by it in the manner described under the caption "Use
of Proceeds" in the Prospectus.

         (i)      Transfer Agent. The Company shall engage and maintain, at its
expense, a registrar and transfer agent for the Company Shares.

         (j)      Earnings Statement. As soon as practicable, the Company will
make generally available to its security holders and to the Representatives an
earnings statement (which need not be audited) covering the twelve-month period
ending [June 30, 2001] that satisfies the provisions of Section 11(a) of the
Securities Act.

         (k)      Periodic Reporting Obligations. During the Prospectus Delivery
Period the Company shall file, on a timely basis, with the Commission and The
Nasdaq National Market all reports and documents required to be filed under the
Exchange Act.



                                       11
<PAGE>   12

         (l)      Agreement Not to Offer or Sell Additional Securities. The
Company will not offer, sell or contract to sell, or otherwise dispose of or
enter into any transaction which is designed to, or could be expected to, result
in the disposition (whether by actual disposition or effective economic
disposition due to cash settlement or otherwise by the Company or any affiliate
of the Company or any person in privity with the Company or any affiliate of the
Company) directly or indirectly, or announce the offering of, any other Common
Shares or any securities convertible into, or exchangeable for, Common Shares;
provided, however, that the Company may (i) issue and sell Common Shares
pursuant to any director or employee stock option plan, stock ownership plan or
dividend reinvestment plan of the Company in effect at the date of the
Prospectus and described in the Prospectus so long as none of those Shares may
be transferred and the Company shall enter stop transfer instructions with its
transfer agent and registrar against the transfer of any such Common Shares and
(ii) the Company may issue Common Shares issuable upon the conversion of
securities or the exercise of warrants outstanding at the date of the Prospectus
and described in the Prospectus. These restrictions terminate after the close of
trading of the Shares on the 180th day of (and including) the day the Shares
commenced trading on The Nasdaq National Market (the "Lock-Up Period").

         (m)      Future Reports to the Representatives. During the period of
five years hereafter the Company will furnish to the Representatives (i) as soon
as practicable after the end of each fiscal year, copies of the Annual Report of
the Company containing the balance sheet of the Company as of the close of such
fiscal year and statements of income, stockholders' equity and cash flows for
the year then ended and the opinion thereon of the Company's independent public
or certified public accountants; (ii) as soon as practicable after the filing
thereof, copies of each proxy statement, Annual Report on Form 10-K, Quarterly
Report on Form 10-Q, Current Report on Form 8-K or other report filed by the
Company with the Commission, the National Association of Securities Dealers,
Inc. or any securities exchange; and (iii) as soon as available, copies of any
report or communication of the Company mailed generally to holders of its
capital stock.

         (n)      Directed Share Program. The Company (i) will comply with all
applicable securities and other applicable laws, rules and regulations in each
jurisdiction in which the Directed Shares are offered in connection with the
Directed Share Program and (ii) will pay all reasonable fees and disbursements
of counsel incurred by the Underwriters in connection with the Directed Share
Program and any stamp duties, similar taxes or duties or other taxes, if any,
incurred by the underwriters in connection with the Directed Share Program.

         SECTION 4.        CONDITIONS OF THE OBLIGATIONS OF THE UNDERWRITERS.

         The obligations of the several Underwriters to purchase and pay for the
Shares as provided herein on the First Closing Date and, with respect to the
Option Shares, the Second Closing Date, shall be subject to the accuracy of the
representations and warranties on the part of the Company set forth in Section 1
hereof as of the date hereof and as of the First Closing Date as though then
made and, with respect to the Option Shares, as of the Second Closing Date as
though then made, to the timely performance by the Company of its covenants and
other obligations hereunder, and to each of the following additional conditions:

         (a)      Compliance with Registration Requirements; No Stop Order; No
Objection from the National Association of Securities Dealers, Inc. The
Registration Statement shall have become effective prior to the execution of
this Agreement, or at such later date as shall be consented to in writing by
you; and no stop order suspending the effectiveness thereof shall have been
issued and no proceedings for that purpose shall have been initiated or, to the


                                       12
<PAGE>   13

knowledge of the Company or any Underwriter, threatened by the Commission, and
any request of the Commission for additional information (to be included in the
Registration Statement or the Prospectus or otherwise) shall have been complied
with to the satisfaction of Underwriters' Counsel; and the National Association
of Securities Dealers, Inc. shall have raised no objection to the fairness and
reasonableness of the underwriting terms and arrangements.

         (b)      Corporate Proceedings. All corporate proceedings and other
legal matters in connection with this Agreement, the form of Registration
Statement and the Prospectus, and the registration, authorization, issue, sale
and delivery of the Shares, shall have been reasonably satisfactory to
Underwriters' Counsel, and such counsel shall have been furnished with such
papers and information as they may reasonably have requested to enable them to
pass upon the matters referred to in this Section.

         (c)      No Material Adverse Change. Subsequent to the execution and
delivery of this Agreement and prior to the First Closing Date, or the Second
Closing Date, as the case may be, there shall not have been any Material Adverse
Change in the condition (financial or otherwise), earnings, operations, business
or business prospects of the Company from that set forth in the Registration
Statement or Prospectus, which, in your sole judgment, is material and adverse
and that makes it, in your sole judgment, impracticable or inadvisable to
proceed with the public offering of the Shares as contemplated by the
Prospectus; and

         (d)      Opinion of Counsel for the Company. You shall have received on
the First Closing Date, or the Second Closing Date, as the case may be, an
opinion of Hale and Dorr LLP, counsel for the Company [MARK: SHOULD WE BREAK
THIS INTO TWO OPINIONS?] substantially in the form of Exhibit B attached hereto,
dated the First Closing Date, or the Second Closing Date, addressed to the
Underwriters and with reproduced copies or signed counterparts thereof for each
of the Underwriters.

                  Counsel rendering the opinion contained in Exhibit B may rely
as to questions of law not involving the laws of the United States or the
District of Columbia and North Carolina upon opinions of local counsel, and as
to questions of fact upon representations or certificates of officers of the
Company, and of government officials, in which case their opinion is to state
that they are so relying and that they have no knowledge of any material
misstatement or inaccuracy in any such opinion, representation or certificate.
Copies of any opinion, representation or certificate so relied upon shall be
delivered to you, as Representatives of the Underwriters, and to Underwriters'
Counsel.


         [(e)     Opinion of Intellectual property Counsel for the Company. You
shall have received on the First Closing Date, or the Second Closing Date, as
the case may be, an opinion of [NAME OF PATENT COUNSEL], intellectual property
counsel for the Company substantially in the form of Exhibit C attached hereto.]


         (f)      Opinion of Counsel for the Underwriters. You shall have
received on the First Closing Date or the Second Closing Date, as the case may
be, an opinion of Alston & Bird LLP substantially in the form of Exhibit D
hereto. The Company shall have furnished to such counsel such documents as they
may have requested for the purpose of enabling them to pass upon such matters.

         (g)      Accountants' Comfort Letter. You shall have received on the
First Closing Date and on the Second Closing Date, as the case may be, a letter
from Deloitte & Touche LLP addressed to the Underwriters, dated the First
Closing Date or the Second Closing Date, as the


                                       13
<PAGE>   14

as the case may be, confirming that they are independent certified public
accountants with respect to the Company within the meaning of the Securities Act
and the applicable published Rules and Regulations and based upon the procedures
described in such letter delivered to you concurrently with the execution of
this Agreement (herein called the "Original Letter"), but carried out to a date
not more than four (4) business days prior to the First Closing Date or the
Second Closing Date, as the case may be, (i) confirming, to the extent true,
that the statements and conclusions set forth in the Original Letter are
accurate as of the First Closing Date or the Second Closing Date, as the case
may be, and (ii) setting forth any revisions and additions to the statements and
conclusions set forth in the Original Letter which are necessary to reflect any
changes in the facts described in the Original Letter since the date of such
letter, or to reflect the availability of more recent financial statements, data
or information. The letter shall not disclose any change in the condition
(financial or otherwise), earnings, operations, business or business prospects
of the Company from that set forth in the Registration Statement or Prospectus,
which, in your sole judgment, is material and adverse and that makes it, in your
sole judgment, impracticable or inadvisable to proceed with the public offering
of the Shares as contemplated by the Prospectus. The Original Letter from
Deloitte & Touche LLP shall be addressed to or for the use of the Underwriters
in form and substance satisfactory to the Underwriters and shall (i) represent,
to the extent true, that they are independent certified public accountants with
respect to the Company within the meaning of the Securities Act and the
applicable published Rules and Regulations, (ii) set forth their opinion with
respect to their examination of the balance sheet of the Company as of December
31, 1999 and related statements of operations, shareholders' equity, and cash
flows for the twelve (12) months ended December 31, 1999, (iii) state that
Deloitte & Touche LLP has performed the procedures set out in Statement on
Auditing Standards No. 71 ("SAS 71") for a review of interim financial
information and providing the report of Deloitte & Touche LLP as described in
SAS 71 on the financial statements for each of the quarters in the one-quarter
period ended March 31, 2000 (the "Quarterly Financial Statements"), (iv) state
that in the course of such review, nothing came to their attention that leads
them to believe that any material modifications need to be made to any of the
Quarterly Financial Statements in order for them to be in compliance with
generally accepted accounting principles consistently applied across the periods
presented, and address other matters agreed upon by Deloitte & Touche LLP and
you. In addition, you shall have received from Deloitte & Touche LLP a letter
addressed to the Company and made available to you for the use of the
Underwriters stating that their review of the Company's system of internal
accounting controls, to the extent they deemed necessary in establishing the
scope of their examination of the Company's financial statements as of December
31, 2000, did not disclose any weaknesses in internal controls that they
considered to be material weaknesses.

         (h)      Officers' Certificate. You shall have received on the First
Closing Date and the Second Closing Date, as the case may be, a certificate of
the Company, dated the First Closing Date or the Second Closing Date, as the
case may be, signed by the Chief Executive Officer and Chief Financial Officer
of the Company, to the effect that, and you shall be satisfied that:

         (i)      The representations and warranties of the Company in this
         Agreement are true and correct, as if made on and as of the First
         Closing Date or the Second Closing Date, as the case may be, and the
         Company has complied with all the agreements and satisfied all the
         conditions on its part to be performed or satisfied at or prior to the
         First Closing Date or the Second Closing Date, as the case may be;

         (ii)     No stop order suspending the effectiveness of the Registration
         Statement has been issued and no proceedings for that purpose have been
         instituted or are pending or threatened under the Securities Act;


                                       14
<PAGE>   15

         (iii)    When the Registration Statement became effective and at all
         times subsequent thereto up to the delivery of such certificate, the
         Registration Statement and the Prospectus, and any amendments or
         supplements thereto, contained all material information required to be
         included therein by the Securities Act, and in all material respects
         conformed to the requirements of the Securities Act; the Registration
         Statement and the Prospectus, and any amendments or supplements
         thereto, did not and does not include any untrue statement of a
         material fact or omit to state a material fact required to be stated
         therein or necessary to make the statements therein not misleading;
         and, since the effective date of the Registration Statement, there has
         occurred no event required to be set forth in an amended or
         supplemented Prospectus which has not been so set forth; and

         (iv)     Subsequent to the respective dates as of which information is
         given in the Registration Statement and Prospectus, there has not been
         (a) any material adverse change in the condition (financial or
         otherwise), earnings, operations, business or business prospects of the
         Company, (b) any transaction that is material to the Company, except
         transactions entered into in the ordinary course of business, (c) any
         obligation, direct or contingent, that is material to the Company,
         incurred by the Company, except obligations incurred in the ordinary
         course of business, (d) any change in the capital stock or outstanding
         indebtedness of the Company that is material to the Company, (e) any
         dividend or distribution of any kind declared, paid or made on the
         capital stock of the Company, or (f) any loss or damage (whether or not
         insured) to the property of the Company which has been sustained or
         will have been sustained which has a material adverse effect on the
         condition (financial or otherwise), earnings, operations, business or
         business prospects of the Company.

         (i)      Lock-up Agreement from Certain Stockholders of the Company.
The Company shall have obtained and delivered to you an agreement substantially
in the form of Exhibit A attached hereto from each officer and director of the
Company and each beneficial owner of one or more percent of the outstanding
issued share capital of the Company.

         (j)      Nasdaq Listing. The Shares shall have been approved for
listing on The Nasdaq National Market, subject only to official notice of
issuance.

         (k)      Compliance with Prospectus Delivery Requirements. The Company
shall have complied with the provisions of Sections 2(g) and 3(e) hereof with
respect to the furnishing of Prospectuses.

         (l)      Additional Documents. On or before each of the First Closing
Date and the Second Closing Date, as the case may be, the Representatives and
counsel for the Underwriters shall have received such information, documents and
opinions as they may reasonably require for the purposes of enabling them to
pass upon the issuance and sale of the Shares as contemplated herein, or in
order to evidence the accuracy of any of the representations and warranties, or
the satisfaction of any of the conditions or agreements, herein contained.

                  If any condition specified in this Section 4 is not satisfied
when and as required to be satisfied, this Agreement may be terminated by the
Representatives by notice to the Company at any time on or prior to the First
Closing Date and, with respect to the Option Shares, at any time prior to the
Second Closing Date, which termination shall be without liability


                                       15
<PAGE>   16

on the part of any party to any other party, except that Section 5 (Payment of
Expenses), Section 6 (Reimbursement of Underwriters' Expenses), Section 7
(Indemnification and Contribution) and Section 10 (Representations and
Indemnities to Survive Delivery) shall at all times be effective and shall
survive such termination.

         SECTION 5.        PAYMENT OF EXPENSES.

                  The Company agrees to pay all costs, fees and expenses

the Representatives, preparing and printing a "Blue Sky Survey", an

pursuant to Section 4, Section 8, or Section 9, or if the sale to the
Underwriters of the Shares on the First Closing Date is not consummated because
of any refusal, inability or failure on the part of the Company to perform any
agreement herein or to comply with any provision hereof, the Company agrees to
reimburse the Representatives and the other Underwriters (or such Underwriters
as have terminated this Agreement with respect to themselves), severally, upon
demand for all out-of-pocket expenses that shall have been reasonably incurred
by the Representatives and the Underwriters in connection with the proposed
purchase and the offering and sale of the Shares, including but not limited to

<PAGE>   17

         (a)      Indemnification of the Underwriters.

         (1)      The Company agrees to indemnify and hold harmless each
Underwriter, its officers and employees, and each person, if any, who controls
any Underwriter within the meaning of the Securities Act and the Exchange Act
against any loss, claim, damage, liability or expense, as incurred, to which
such Underwriter or such controlling person may become subject, under the
Securities Act, the Exchange Act or other federal or state statutory law or
regulation, or at common law or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of the
Company, which consent shall not be unreasonably withheld), insofar as such
loss, claim, damage, liability or expense (or actions in respect thereof as
contemplated below) arises out of or is based (i) upon any untrue statement or
alleged untrue statement of a material fact contained in the Registration
Statement, or any amendment thereto, including any information deemed to be a
part thereof pursuant to Rule 430A under the Securities Act, or the omission or
alleged omission therefrom of a material fact required to be stated therein or
necessary to make the statements therein not misleading; or (ii) upon any untrue
statement or alleged untrue statement of a material fact contained in any
preliminary prospectus or the Prospectus (or any amendment or supplement
thereto), or the omission or alleged omission therefrom of a material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading; or (iii) in whole or
in part upon any inaccuracy in the representations and warranties of the Company
contained herein; or (iv) in whole or in part upon any failure of the Company to
perform its obligations hereunder or under law; or (v) any untrue statement or
alleged untrue statement of any material fact contained in any audio or visual
materials provided by the Company or based upon written information furnished by
or on behalf of the Company including, without limitation, slides, videos, films
or tape recordings, used in connection with the marketing of the Shares or (vi)
any act or failure to act or any alleged act or failure to act by any
Underwriter in connection with, or relating in any manner to, the Shares or the
offering contemplated hereby, and which is included as part of or referred to in
any loss, claim, damage, liability or action arising out of or based upon any
matter covered by clause (i), (ii), (iii), (iv) or (v) above, provided that the
Company shall not be liable under this clause (vi) to the extent that a court of
competent jurisdiction shall have determined by a final judgment that such loss,
claim, damage, liability or action resulted directly from any such acts or
failures to act undertaken or omitted to be taken by such Underwriter through
its bad faith or willful misconduct; and to reimburse each Underwriter and each
such controlling person for any and all expenses (including the fees and
disbursements of counsel chosen by Robertson Stephens) as such expenses are
reasonably incurred by such Underwriter or such controlling person in connection
with investigating, defending, settling, compromising or paying any such loss,
claim, damage, liability, expense or action; provided, however, that the
foregoing indemnity agreement shall not apply to any loss, claim, damage,
liability or expense to the extent, but only to the extent, arising out of or
based upon any untrue statement or alleged untrue statement or omission or
alleged omission made in reliance upon and in conformity with written
information furnished to the Company by the Representatives expressly for use in
the Registration Statement, any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto). The indemnity agreement set forth in this
Section 7(a) shall be in addition to any liabilities that the Company may
otherwise have.

         (b)      Indemnification of the Company and its Directors and Officers.
Each Underwriter agrees, severally and not jointly, to indemnify and hold
harmless the Company, each of its directors, each of its officers who signed the
Registration Statement, and each person, if any, who controls the Company within
the meaning of the Securities Act or the Exchange Act, against any loss, claim,
damage, liability or expense, as incurred, to which the Company, or any


                                       17
<PAGE>   18

such director, officer or controlling person may become subject, under the
Securities Act, the Exchange Act, or other federal or state statutory law or
regulation, or at common law or otherwise (including in settlement of any
litigation, if such settlement is effected with the written consent of such
Underwriter), insofar as such loss, claim, damage, liability or expense (or
actions in respect thereof as contemplated below) arises out of or is based upon
any untrue or alleged untrue statement of a material fact contained in the
Registration Statement, any preliminary prospectus or the Prospectus (or any
amendment or supplement thereto), or arises out of or is based upon 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, in each case
to the extent, but only to the extent, that such untrue statement or alleged
untrue statement or omission or alleged omission was made in the Registration
Statement, any preliminary prospectus, the Prospectus (or any amendment or
supplement thereto), in reliance upon and in conformity with written information
furnished to the Company by the Representatives expressly for use therein; and
to reimburse the Company, or any such director, officer or controlling person
for any legal and other expense reasonably incurred by the Company, or any such
director, officer or controlling person in connection with investigating,
defending, settling, compromising or paying any such loss, claim, damage,
liability, expense or action. The indemnity agreement set forth in this Section
7(b) shall be in addition to any liabilities that each Underwriter may otherwise
have.


         (c)      Information Provided by the Underwriters. The Company and each
person, if any, who controls the Company within the meaning of the Securities
Act or the Exchange Act, hereby acknowledges that the only information that the
Underwriters have furnished to the Company expressly for use in the Registration
Statement, any preliminary prospectus or the Prospectus (or any amendment or
supplement thereto) are the statements set forth in the table in the first
paragraph and the [________ and _________ paragraphs] under the caption
"Underwriting" in the Prospectus; and the Underwriters confirm that such
statements are correct.


         (d)      Notifications and Other Indemnification Procedures. Promptly
after receipt by an indemnified party under this Section 7 of notice of the
commencement of any action, such indemnified party will, if a claim in respect
thereof is to be made against an indemnifying party under this Section 7, notify
the indemnifying party in writing of the commencement thereof, but the omission
so to notify the indemnifying party will not relieve it from any liability which
it may have to any indemnified party for contribution or otherwise under the
indemnity agreement contained in this Section 7 or to the extent it is not
prejudiced as a proximate result of such failure. In case any such action is
brought against any indemnified party and such indemnified party seeks or
intends to seek indemnity from an indemnifying party, the indemnifying party
will be entitled to participate in, and, to the extent that it shall elect,
jointly with all other indemnifying parties similarly notified, by written
notice delivered to the indemnified party promptly after receiving the aforesaid
notice from such indemnified party, to assume the defense thereof with counsel
reasonably satisfactory to such indemnified party; provided, however, if the
defendants in any such action include both the indemnified party and the
indemnifying party and the indemnified party shall have reasonably concluded
that a conflict may arise between the positions of the indemnifying party and
the indemnified party in conducting the defense of any such action or that there
may be legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
assume such legal defenses and to otherwise participate in the defense of such
action on behalf of such indemnified party or parties. Upon receipt of notice
from the indemnifying party to such indemnified party of such indemnifying
party's election so to assume the defense of such action


                                       18
<PAGE>   19

and approval by the indemnified party of counsel, the indemnifying party will
not be liable to such indemnified party under this Section 7 for any legal or
other expenses subsequently incurred by such indemnified party in connection
with the defense thereof unless (i) the indemnified party shall have employed
separate counsel in accordance with the proviso to the next preceding sentence
(it being understood, however, that the indemnifying party shall not be liable
for the expenses of more than one separate counsel (together with local
counsel), approved by the indemnifying party (Robertson Stephens in the case of
Section 7(b) and Section 8), representing the indemnified parties who are
parties to such action), (ii) the indemnifying party shall not have employed
counsel satisfactory to the indemnified party to represent the indemnified party
within a reasonable time after notice of commencement of the action, or (iii)
the indemnifying party has authorized the employment of counsel for the
indemnified party at the expense of the indemnifying party, in each of which
cases the fees and expenses of counsel shall be at the expense of the
indemnifying party.

         (e)      Settlements. The indemnifying party under this Section 7 shall
not be liable for any settlement of any proceeding effected without its written
consent, which consent shall not be unreasonably withheld, but if settled with
such consent or if there be a final judgment for the plaintiff, the indemnifying
party agrees to indemnify the indemnified party against any loss, claim, damage,
liability or expense by reason of such settlement or judgment. Notwithstanding
the foregoing sentence, if at any time an indemnified party shall have requested
an indemnifying party to reimburse the indemnified party for fees and expenses
of counsel as contemplated by Section 7(d) hereof, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if (i) such settlement is entered into more than 60 days
after receipt by such indemnifying party of the aforesaid request and (ii) such
indemnifying party shall not have reimbursed the indemnified party in accordance
with such request prior to the date of such settlement. No indemnifying party
shall, without the prior written consent of the indemnified party, effect any
settlement, compromise or consent to the entry of judgment in any pending or
threatened action, suit or proceeding in respect of which any indemnified party
is or could have been a party and indemnity was or could have been sought
hereunder by such indemnified party, unless such settlement, compromise or
consent includes (i) an unconditional release of such indemnified party from all
liability on claims that are the subject matter of such action, suit or
proceeding and (ii) does not include a statement as to or an admission of fault,
culpability or a failure to act by or on behalf of any indemnified party.

         (f)      Contribution. If the indemnification provided for in this
Section 7 is unavailable to or insufficient to hold harmless an indemnified
party under Section 7(a) or (b) above in respect of any losses, claims, damages
or liabilities (or actions or proceedings in respect thereof) then each
indemnifying party shall contribute to the aggregate amount paid or payable by
such indemnified party in such proportion as is appropriate to reflect the
relative benefits received by such party on the one hand and the Underwriters on
the other from the offering of the Shares. If, however, the allocation provided
by the immediately preceding sentence is not permitted by applicable law then
each indemnifying party shall contribute to such amount paid or payable by such
indemnified party in such proportion as is appropriate to reflect not only such
relative benefits but also the relative fault of the such party on the one hand
and the Underwriters on the other in connection with the statements or omissions
which resulted in such losses, claims, damages or liabilities, (or actions or
proceedings in respect thereof), as well as any other relevant equitable
considerations. The relative fault shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material fact
or the omission or alleged omission to state a material fact relates to
information supplied by the Company on the one hand or the Underwriters on the
other and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.


                                       19
<PAGE>   20

                  The Company and Underwriters agree that it would not be just
and equitable if contributions pursuant to this Section 7(f) were determined by
pro rata allocation (even if the Underwriters were treated as one entity for
such purpose) or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 7(f). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions or proceedings in respect thereof)
referred to above in this Section 7(f) shall be deemed to include any legal or
other expenses reasonably incurred by such indemnified party in connection with
investigating or defending any such action or claim. Notwithstanding the
provisions of this subsection (f), (i) no Underwriter shall be required to
contribute any amount in excess of the underwriting discounts and commissions
applicable to the Shares purchased by such Underwriter and (ii) no person guilty
of fraudulent misrepresentation (within the meaning of Section 11(f) of the
Securities Act) shall be entitled to contribution from any person who was not
guilty of such fraudulent misrepresentation. The Underwriters' obligations in
this Section 7(f) to contribute are several in proportion to their respective
underwriting obligations and not joint.

         (g)      Timing of Any Payments of Indemnification. Any losses, claims,
damages, liabilities or expenses for which an indemnified party is entitled to
indemnification or contribution under this Section 7 shall be paid by the
indemnifying party to the indemnified party as such losses, claims, damages,
liabilities or expenses are incurred, but in all cases, no later than forty-five
(45) days of invoice to the indemnifying party.

         (h)      Survival. The indemnity and contribution agreements contained
in this Section 7 and the representation and warranties set forth in this
Agreement shall remain operative and in full force and effect, regardless of (i)
any investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter, the Company, its directors or officers or any
persons controlling the Company, (ii) acceptance of any Shares and payment
therefor hereunder, and (iii) any termination of this Agreement. A successor to
any Underwriter, or to the Company, its directors or officers, or any person
controlling the Company, shall be entitled to the benefits of the indemnity,
contribution and reimbursement agreements contained in this Section 7.

         (i)      Acknowledgements of Parties. The parties to this Agreement
hereby acknowledge that they are sophisticated business persons who were
represented by counsel during the negotiations regarding the provisions hereof
including, without limitation, the provisions of this Section 7, and are fully
informed regarding said provisions. They further acknowledge that the provisions
of this Section 7 fairly allocate the risks in light of the ability of the
parties to investigate the Company and its business in order to assure that
adequate disclosure is made in the Registration Statement and Prospectus as
required by the Securities Act and the Exchange Act.

         (j)      Indemnification for Directed Share Program. The Company agrees
to indemnify and hold harmless Robertson Stephens and its affiliates and each
person, if any, who controls Robertson Stephens or its affiliates within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act ("Robertson Stephens Entities"), from and against any and all losses,
claims, damages and liabilities (including, without limitation, any legal or
other expenses reasonably incurred in connection with defending or investigating
any such action or claim) (i) caused by any untrue statement or alleged untrue
statement of a material fact contained in any material prepared by or with the
consent of the Company for distribution to participants in connection with the
Directed Share Program, or caused by any omission or alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading; (ii) the failure of any participant to pay
for and accept delivery of


                                       20
<PAGE>   21

Directed Shares that the participant has agreed to purchase; or (iii) related
to, arising out of, or in connection with the Directed Share Program other than
losses, claims, damages or liabilities (or expenses relating thereto) that are
finally judicially determined to have resulted from the bad faith of Robertson
Stephens Entities.

         SECTION 8. DEFAULT OF ONE OR MORE OF THE SEVERAL UNDERWRITERS.

                  If, on the First Closing Date or the Second Closing Date, as
the case may be, any one or more of the several Underwriters shall fail or
refuse to purchase Shares that it or they have agreed to purchase hereunder on
such date, and the aggregate number of Common Shares which such defaulting
Underwriter or Underwriters agreed but failed or refused to purchase does not
exceed 10% of the aggregate number of the Shares to be purchased on such date,
the other Underwriters shall be obligated, severally, in the proportions that
the number of Firm Common Shares set forth opposite their respective names on
Schedule A bears to the aggregate number of Firm Shares set forth opposite the
names of all such non-defaulting Underwriters, or in such other proportions as
may be specified by the Representatives with the consent of the non-defaulting
Underwriters, to purchase the Shares which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date. If, on the
First Closing Date or the Second Closing Date, as the case may be, any one or
more of the Underwriters shall fail or refuse to purchase Shares and the
aggregate number of Shares with respect to which such default occurs exceeds 10%
of the aggregate number of Shares to be purchased on such date, and arrangements
satisfactory to the Representatives and the Company for the purchase of such
Shares are not made within 48 hours after such default, this Agreement shall
terminate without liability of any party to any other party except that the
provisions of Section 5, Section 6 and Section 7 shall at all times be effective
and shall survive such termination. In any such case either the Representatives
or the Company shall have the right to postpone the First Closing Date or the
Second Closing Date, as the case may be, but in no event for longer than seven
days in order that the required changes, if any, to the Registration Statement
and the Prospectus or any other documents or arrangements may be effected.

                  As used in this Agreement, the term "Underwriter" shall be
deemed to include any person substituted for a defaulting Underwriter under this
Section 8. Any action taken under this Section 8 shall not relieve any
defaulting Underwriter from liability in respect of any default of such
Underwriter under this Agreement.

         SECTION 9. TERMINATION OF THIS AGREEMENT.

                  This Agreement may be terminated by the Representatives by
notice given to the Company if (a) at any time after the execution and delivery
of this Agreement and prior to the First Closing Date (i) trading or quotation
in any of the Company's securities shall have been suspended or limited by the
Commission or by The Nasdaq Stock Market, or trading in securities generally on
either The Nasdaq Stock Market or the New York Stock Exchange shall have been
suspended or limited, or minimum or maximum prices shall have been generally
established on any of such stock exchanges by the Commission or the National
Association of Securities Dealers, Inc.; (ii) a general banking moratorium shall
have been declared by any of federal, New York or California authorities; (iii)
there shall have occurred any outbreak or escalation of national or
international hostilities or any crisis or calamity, or any change in the United
States or international financial markets, or any substantial change or
development involving a prospective change in United States' or international
political, financial or economic conditions, as in the judgment of the
Representatives is material and adverse and makes it


                                       21
<PAGE>   22

impracticable or inadvisable to market the Common Shares in the manner and on
the terms contemplated in the Prospectus or to enforce contracts for the sale of
securities; (iv) in the judgment of the Representatives there shall have
occurred any Material Adverse Change; or (v) the Company shall have sustained a
loss by strike, fire, flood, earthquake, accident or other calamity of such
character as in the judgment of the Representatives may interfere materially
with the conduct of the business and operations of the Company regardless of
whether or not such loss shall have been insured or (b) in the case of any of
the events specified 9(a)(i)-(v), such event singly or together with any other
event, makes it, in your judgement, impracticable or inadvisable to market the
Common Shares in the manner and on the terms contemplated in the Prospectus. Any
termination pursuant to this Section 9 shall be without liability on the part of
(x) the Company to any Underwriter, except that the Company shall be obligated
to reimburse the expenses of the Representatives and the Underwriters pursuant
to Sections 5 and 6 hereof, (y) any Underwriter to the Company or any person
controlling the Company, or (z) of any party hereto to any other party except
that the provisions of Section 7 shall at all times be effective and shall
survive such termination.

         SECTION 10. REPRESENTATIONS AND INDEMNITIES TO SURVIVE DELIVERY.

                  The respective indemnities, agreements, representations,
warranties and other statements of the Company or any person controlling the
company, of its officers, and of the several Underwriters set forth in or made
pursuant to this Agreement will remain in full force and effect, regardless of
any investigation made by or on behalf of any Underwriter or the Company or any
of its or their partners, officers or directors or any controlling person, and
will survive delivery of and payment for the Shares sold hereunder and any
termination of this Agreement.

         SECTION 11. NOTICES.

         SECTION 13. PARTIAL UNENFORCEABILITY.

         RE:  YOUCentric, Inc. (the "Company")

Ladies & Gentlemen:

                  The undersigned is an owner of record or beneficially of
certain shares of the Common Stock of the Company ("Common Stock") or securities
convertible into or exchangeable or exercisable for Common Stock. The Company
proposes to carry out a public offering of Common Stock (the "Offering") for
which you will act as the representatives (the "Representatives") of the
underwriters. The undersigned recognizes that the Offering will be of benefit to
the undersigned and will benefit the Company by, among other things, raising
additional capital for its operations. The undersigned acknowledges that you and
the other underwriters are relying on the representations and agreements of the
undersigned contained in this letter in carrying out the Offering and in
entering into underwriting arrangements with the Company with respect to the
Offering.

                  In consideration of the foregoing, the undersigned hereby
agrees that the undersigned will not offer to sell, contract to sell, or
otherwise sell, dispose of, loan, pledge or grant any rights with respect to
(collectively, a "Disposition") any shares of Common Stock, any options or
warrants to purchase any shares of Common Stock or any securities convertible
into or exchangeable for shares of Common Stock (collectively, "Securities") now
owned or hereafter acquired directly by such person or with respect to which
such person has or hereafter acquires the power of disposition, otherwise than
(i) as a bona fide gift or gifts, provided the donee or donees thereof agree in
writing to be bound by this restriction, (ii) as a distribution to partners or
shareholders of such person, provided that the distributees thereof agree in
writing to be bound by the terms of this restriction, (iii) with respect to
sales or purchases of Common Stock acquired on the open market, (iv) with
respect to shares received in the Directed Share Program, as such term shall be
defined in the Underwriting Agreement between the Company and the
Representatives, or (v) with the prior written consent of FleetBoston Robertson
Stephens Inc. The foregoing restrictions will terminate after the close of
trading of the Common Stock on the 180th day of (and including) the day the
Common Stock commenced trading on the Nasdaq National Market (the "Lock-Up"
Period). The foregoing restriction has been expressly agreed to preclude the
holder of the Securities from engaging in any hedging or other transaction which
is designed to or reasonably expected to lead to or result in a Disposition of
Securities during the Lock-up Period, even if such Securities would be disposed
of by someone other than such holder. Such prohibited hedging or other
transactions would include, without limitation, any short sale (whether or not
against the box) or any purchase, sale or grant of any right (including, without
limitation, any put or call option) with respect to any Securities or with
respect to any security (other than a broad-based market basket or index) that
included, relates

to or derives any significant part of its value from Securities. The undersigned
also agrees and consents to the entry of stop transfer instructions with the
Company's transfer agent and registrar against the transfer of shares of Common
Stock or Securities held by the undersigned except in compliance with the
foregoing restrictions.

                  This agreement is irrevocable and will be binding on the
undersigned and the respective successors, heirs, personal representatives, and
assigns of the undersigned. In the event the Offering has not occurred on or
before July 31, 2000, this Lock-Up Agreement shall be of no further force or
effect.

         (x)      The Registration Statement and the Prospectus, and each
         amendment or supplement thereto (other than the financial statements

         (xi)     The information in the Prospectus under the caption
         "Description of Capital Stock," to the extent that it constitutes
         matters of law or legal conclusions, has been reviewed by such counsel
         and is a fair summary of such matters and conclusions; and the forms of
         certificates evidencing the Common Stock and filed as exhibits to the
         Registration Statement comply with North Carolina law;

         (xii)    The description in the Registration Statement and the

         (xiii)   To such counsel's knowledge, there are no agreements,
         contracts, leases or documents to which the Company is a party of a
         character required to be described or referred to in the Registration
         Statement or Prospectus or to be filed as an exhibit to the
         Registration Statement which are not described or referred to therein
         or filed as required;

         (xiv)    The performance of this Agreement and the consummation of the
         transactions herein contemplated (other than performance of the
         Company's indemnification obligations hereunder, concerning which no
         opinion need be expressed) will not (a) result in any violation of the
         Company's charter or bylaws or (b) to such counsel's knowledge, result
         in a material breach or violation of any of the terms and provisions
         of, or constitute a default under, any bond, debenture, note or other
         evidence of indebtedness, or any lease, contract, indenture, mortgage,
         deed of trust, loan agreement, joint venture or other agreement or
         instrument known to such counsel to which the Company is a party or by
         which its properties are bound, or any applicable statute, rule or
         regulation known to such counsel or, to such counsel's knowledge, any
         order, writ or decree of any court, government or governmental agency

<PAGE>   31

         over any of its properties or operations is necessary in connection
         with the consummation by the Company of the transactions herein
         contemplated, except (i) such as have been obtained under the
         Securities Act, (ii) such as may be required under state or other
         securities or Blue Sky laws in connection with the purchase and the
         distribution of the Shares by the Underwriters, (iii) such as may be
         required by the National Association of Securities Dealers, Inc. and
         (iv) such as may be required under the federal or provincial laws of
         Canada;

         (xvi)    To such counsel's knowledge, there are no legal or
         governmental proceedings pending or threatened against the Company of a
         character required to be disclosed in the Registration Statement or the
         Prospectus by the Securities Act, other than those described therein;

         (xvii)   To such counsel's knowledge, the Company is not presently (a)
         in material violation of its respective charter or bylaws, or (b) in
         material breach of any applicable statute, rule or regulation known to
         such counsel or, to such counsel's knowledge, any order, writ or decree
         of any court or governmental agency or body having jurisdiction over
         the Company or over any of their properties or operations; and

         (xviii)  To such counsel's knowledge, except as set forth in the
         Registration Statement and Prospectus, no holders of Company Shares or
         other securities of the Company have registration rights with respect
         to securities of the Company and, except as set forth in the
         Registration Statement and Prospectus, all holders of securities of the
         Company having rights known to such counsel to registration of such
         shares of Company Shares or other securities, because of the filing of
         the Registration Statement by the Company have, with respect to the
         offering contemplated thereby, waived such rights or such rights have
         expired by reason of lapse of time following notification of the
         Company's intent to file the Registration Statement or have included
         securities in the Registration Statement pursuant to the exercise of
         and in full satisfaction of such rights.

         and the sale of the Shares and the application of the proceeds thereof
         as described in the Prospectus, will not be, an "investment company" as
         such term is defined in the Investment Company Act of 1940, as amended.

         [(xx) To such counsel's knowledge, the Company owns or possesses
         sufficient trademarks, trade names, patent rights, copyrights,
         licenses, approvals, trade secrets and other similar rights
         (collectively, "Intellectual Property Rights") reasonably necessary to
         conduct their business as now conducted; and the expected expiration of
         any such Intellectual Property Rights would not result in a Material
         Adverse Effect. The Company has not received any notice of infringement
         or conflict with asserted Intellectual Property Rights of others, which
         infringement or conflict, if the subject of an unfavorable decision,
         would result in a Material Adverse Effect. To such counsel's knowledge,
         the Company's discoveries, inventions, products, or processes referred
         to in the Registration Statement or Prospectus do not infringe or
         conflict with any right or patent which is the subject of a patent
         application known to the Company.]

                  In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, the Representatives, Underwriters' Counsel and the independent
certified public accountants of the Company, at


                                      B-3
<PAGE>   32

which such conferences the contents of the Registration Statement and Prospectus
and related matters were discussed, and although they have not verified the
accuracy or completeness of the statements contained in the Registration
Statement or the Prospectus, nothing has come to the attention of such counsel
which leads them to believe that, at the time the Registration Statement became
effective and at all times subsequent thereto up to and on the First Closing
Date or Second Closing Date, as the case may be, the Registration Statement and
any amendment or supplement thereto (other than the financial statements
including supporting schedules and other financial and statistical information
derived therefrom, as to which such counsel need express no comment) contained
any untrue statement of a material fact or omitted to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or at the First Closing Date or the Second Closing Date, as the case
may be, the Registration Statement, the Prospectus and any amendment or
supplement thereto [and any Incorporated Document] (except as aforesaid)
contained any untrue statement of a material fact or omitted to state a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.

                                   EXHIBIT C

                    MATTERS TO BE COVERED IN THE OPINION OF
                 INTELLECTUAL PROPERTY COUNSEL FOR THE COMPANY

                  Such counsel are familiar with the technology used by the
Company in its business and the manner of its use thereof and have read the
Registration Statement and the Prospectus, including particularly the portions
of the Registration Statement and the Prospectus referring to patents, trade
secrets, trademarks, service marks or other proprietary information or materials
and:

         (i)      As to the statements under the captions "Risk Factors--
         Dependence on Patents and Proprietary Rights" and "Business-- [Patents]
         and Proprietary Rights," nothing has come to the attention of such
         counsel which caused them to believe that the above-mentioned sections
         of the Registration Statement and any amendment or supplement thereto
         made available and reviewed by such counsel, at the time the
         Registration Statement became effective and at all times subsequent
         thereto up to and on the Closing Date and on any later date on which
         Option Stock are to be purchased, contained any untrue statement of a
         material fact or omitted to state a material fact required to be stated
         therein or necessary to make the statements therein, in light of the
         circumstances under which they were made, not misleading;

         (ii)     Such counsel knows of no material action, suit, claim or
         proceeding relating to patents, patent rights or licenses, trademarks
         or trademark rights, copyrights, collaborative research, licenses or
         royalty arrangements or agreements or trade secrets, know-how or
         proprietary techniques, including processes and substances, owned by or
         affecting the business or operations of the Company which are pending
         or threatened against the Company or any of its officers or directors.

         (iii)    The Company is listed in the records of the United States
         Patent and Trademark Office as the holder of record of the patents
         listed on a schedule to such opinion (the "Patents") and each of the
         applications listed on a schedule to such opinion (the "Applications").
         To the knowledge of such counsel, there are no claims of third parties
         to any ownership interest or lien with respect to any of the Patents or
         Applications. Such counsel is not aware of any material defect in form
         in the preparation or filing of the Applications on behalf of the
         Company. To the knowledge of such counsel, the Applications are being
         pursued by the Company. To the knowledge of such counsel, the Company
         owns as its sole property the Patents and pending Applications;

         (iv)     The Company is listed in the records of the appropriate
         foreign offices as the sole holder of record of the foreign patents
         listed on a schedule to such opinion (the "Foreign Patents") and each
         of the applications listed on a schedule to such opinion (the "Foreign
         Applications"). Such counsel knows of no claims of third parties to any
         ownership interest or lien with respect to the Foreign Patents or
         Foreign Applications. Such counsel is not aware of any material defect
         of form in the preparation or filing of the Foreign Applications on
         behalf of the Company. To the knowledge of such counsel, the Foreign
         Applications are being pursued by the Company. To the knowledge of such
         counsel, the Company owns as its sole property the Foreign Patents and
         pending Foreign Applications; and


                                      C-1
<PAGE>   34

         (v)      Such counsel knows of no reason why the Patents or Foreign
         Patents are not valid as issued. Such counsel has no knowledge of any
         reason why any patent to be issued as a result of any Application or
         Foreign Application would not be valid or would not afford the Company
         useful patent protection with respect thereto;

                                    EXHIBIT D

          MATTERS TO BE COVERED IN THE OPINION OF UNDERWRITERS' COUNSEL

         (i)      The Shares to be issued by the Company have been duly
         authorized and, upon issuance and delivery and payment therefor in
         accordance with the terms of the Underwriting Agreement, will be
         validly issued, fully paid and non-assessable.

         (ii)     The Registration Statement complied as to form in all material
         respects with the requirements of the Securities Act; the Registration
         Statement has become effective under the Securities Act and, to such
         counsel's knowledge, no stop order proceedings with respect thereto
         have been instituted or threatened or are pending under the Securities
         Act.

         (iii)    The 8-A Registration Statement complied as to form in all
         material respects with the requirements of the Exchange Act; the 8-A
         Registration Statement has become effective under the Exchange Act; and
         the Shares have been validly registered under the Securities Act and
         the Rules and Regulations of the Exchange Act and the applicable rules
         and regulations of the Commission thereunder;

         (iv)     The Underwriting Agreement has been duly authorized, executed
         and delivered by the Company.

                  Such counsel shall state that such counsel has reviewed the
opinions addressed to the Representatives from [_________________], each dated
the date hereof, and furnished to you in accordance with the provisions of the
Underwriting Agreement. Such opinions appear on their face to be appropriately
responsive to the requirements of the Underwriting Agreement.

                  In addition, such counsel shall state that such counsel has
participated in conferences with officials and other representatives of the
Company, the Representatives, Underwriters' Counsel and the independent
certified public accountants of the Company, at which such conferences the
contents of the Registration Statement and Prospectus and related matters were
discussed, and although they have not verified the accuracy or completeness of
the statements contained in the Registration Statement or the Prospectus,
nothing has come to the attention of such counsel which leads them to believe

subsequent thereto up to and on the First Closing Date or Second Closing Date,
as the case may be, the Registration Statement and any amendment or supplement
thereto (other than the financial statements including supporting schedules and
other financial and statistical information derived therefrom, as to which such
counsel need express no comment) contained any untrue statement of a material
fact or omitted to state a material fact required to be stated therein or
necessary to make the statements therein not misleading, or at the First Closing
Date or the Second Closing Date, as the case may be, the Registration Statement,
the Prospectus and any amendment or supplement thereto (except as aforesaid)
contained any untrue statement of a material fact or omitted to state a material
fact necessary to make the statements therein, in the light of the circumstances
under which they were made, not misleading.
