(1) Includes (i) the estimated number of shares of Common Stock that may be
issued upon conversion of the Series A Convertible Preferred Stock issued or
issuable to certain of the selling stockholders, based on a conversion price
equal to 75% of the average closing bid price of the Common Stock for the five
(5) trading days ending on May 12, 1998 and (ii) 150,000 shares of Common Stock
held by a selling stockholder who is an affiliate of the Company. Pursuant to
Rule 416 of the Securities Act of 1933, as amended (the "Securities Act"), there
are also being registered hereunder such additional shares as may be issued as a
result of (x) accrued but unpaid dividends on the Series A Convertible Preferred
Stock, (y) any increase in the number of shares of Common Stock issuable upon
conversion of the Series A Convertible Preferred Stock by reason of the floating

price per share of the Common Stock, as reported on the Nasdaq SmallCap Market
System on May 11, 1998.

THE INFORMATION CONTAINED HEREIN IS SUBJECT TO COMPLETION OR AMENDMENT. A
REGISTRATION STATEMENT RELATING TO THESE SECURITIES HAS BEEN FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION. THESE SECURITIES MAY NOT BE SOLD NOR MAY
OFFERS TO BUY BE ACCEPTED PRIOR TO THE TIME THE REGISTRATION STATEMENT BECOMES
EFFECTIVE. THIS PROSPECTUS SHALL NOT CONSTITUTE AN OFFER TO SELL OR THE
SOLICITATION OF AN OFFER TO BUY NOR SHALL THERE BE ANY SALE OF THESE SECURITIES
IN ANY JURISDICTION IN WHICH SUCH OFFER, SOLICITATION OR SALE WOULD BE UNLAWFUL
PRIOR TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF ANY SUCH
JURISDICTION.

                              SUBJECT TO COMPLETION
                   PRELIMINARY PROSPECTUS DATED MAY 14, 1998

                                1,638,375 SHARES

                          NHANCEMENT TECHNOLOGIES INC.

                                  COMMON STOCK

         All of the shares of Common Stock, $0.01 par value ("Common Stock"), of
NHancement Technologies Inc., a Delaware corporation (the "Company" or
"NHancement"), offered hereby are being sold by certain stockholders of the
Company named herein under "Selling Stockholders" and may be offered for sale
from time to time by and for the account of such stockholders (collectively, the
"Selling Stockholders") as more fully described herein. See "Selling
Stockholders." Up to 150,000 of the shares offered for sale hereby are held by a
Selling Stockholder who is an affiliate of the Company; such Selling Stockholder
presently holds approximately 18.25% of the issued and outstanding shares of the
Common Stock of the Company. Such shares are being registered pursuant to the
terms of a registration rights agreement entered into between the Company and
such Selling Stockholder in connection with the initial public offering of the
Company's Common Stock in February 1997. The balance of the shares offered for
sale hereby are issuable upon conversion of the Series A Convertible Preferred
Stock of the Company currently held by or to be issued to certain of the Selling
Stockholders. Based on a conversion price equal to 75% of the average closing
bid price of the Common Stock for the five trading days ending on May 12, 1998,
the Series A Convertible Preferred Stock would convert into 1,488,375 shares of
Common Stock. The foregoing estimate is for illustrative purposes only. The
actual number of shares of Common Stock issued or issuable upon conversion of
the Series A Convertible Preferred Stock is subject to adjustment and could be
materially more than such estimated amount, depending upon factors that cannot
be predicted by the Company at this time, including, among others, the future
market price of the Common Stock. See "Risk Factors -- Prior Losses; Uncertainty
of Future Profitability" and "--Potential Volatility of Stock Price." There is
also a limitation on the number of shares of Common Stock that can be issued
upon conversion of the Preferred Stock at any particular time; generally, the
Selling Stockholders holding Series A Convertible Preferred Stock have
contractually agreed with the Company not to convert the Series A Convertible
Preferred Stock to the extent that such conversion would result in a Selling
Stockholder beneficially owning more than 9.99% of the then-outstanding Common
Stock. In addition, the issuance of shares of Series A Convertible Preferred
Stock convertible into Common Stock representing more than 20% of the
then-outstanding Common Stock of the Company requires the approval of the
Company's stockholders, which approval has not yet been solicited or obtained.
For a further description of the terms of the Series A Convertible Preferred
Stock financing, see "Recent Developments."

         The Company will not receive any proceeds from the sale of shares
offered hereby by the Selling Stockholders. See "Use of Proceeds," "Selling
Stockholders" and "Plan of Distribution." The shares are being offered on a
continuous basis pursuant to Rule 415 under the Securities Act of 1933, as
amended (the "Securities Act"), during a period of time commencing on the
effective date of the Registration Statement of which this Prospectus forms a
part and ending on _________________ or the earlier sale of all of the shares
offered hereby.

         The Common Stock is currently listed on the Nasdaq SmallCap Market
System Market under the symbol "NHAN." On May 12, 1998, the closing bid price
per share of the Common Stock on the Nasdaq SmallCap Market System was $3.00.



<PAGE>   4

         The shares may be offered by the Selling Stockholders from time to time
in transactions (which may include block transactions) on the Nasdaq SmallCap
Market System, in negotiated transactions, through a combination of such methods
of sale, or otherwise, at fixed prices that may be changed, at market prices
prevailing at the time of sale, or at negotiated prices. The Selling
Stockholders may effect such transactions by selling the shares to or through
broker-dealers, who may receive compensation in the form of discounts,
concessions or commissions from the Selling Stockholders and/or the purchasers
of the shares for whom such broker-dealers may act as agents or to whom they may
sell as principals, or both (which compensation as to a particular broker-dealer
might be in excess of customary commissions). As of the date of this Prospectus,
no agreements had been reached for the sale of the shares or the amount of any
compensation to be paid to underwriters, brokers or dealers in connection
therewith. The Company has agreed to bear all expenses in connection with the
registration and sale of the shares being offered hereby by the Selling
Stockholders, other than commissions, concessions or discounts to underwriters,
brokers or dealers and certain fees and expenses of counsel and other advisors
to certain of the Selling Stockholders. See "Selling Stockholders" and "Plan of
Distribution." Each of the Selling Stockholders, individually, reserves the sole
right to accept or reject, in whole or in part, any proposed purchase of the
shares to be made in the manner set forth above.

                SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS

         Certain statements included in or incorporated by reference into this
Prospectus constitute "forward-looking statements" within the meaning of the
Private Securities Litigation Reform Act of 1995. Such forward-looking
statements involve known and unknown risks, uncertainties and other factors
which may cause the actual results, performance or achievements of the Company
to be materially different from any future results, performance or achievements
expressed or implied by such forward-looking statements. Such factors include,
among others, the following: general economic and business conditions, which
will, among other things, impact the demand for the Company's products and
services; market demand, which generally tends to increase during strong years
of the business cycle and generally tends to decrease during weak years of the
business cycle, although the Company's historical and future financial
performance may not necessarily conform to these stated trends; product
performance and technological developments, which may affect the Company's
ability to compete with other companies marketing products or performing
services similar to those marketed or performed by the Company, thereby
affecting the Company's ability, among other things, to generate revenues;
changes in the Company's business strategy or development plans, which may,
among other things, prolong the time it takes to achieve the Company's
objectives described herein; the loss of any significant suppliers or customers;
the Company's dependence on key personnel; the quality, judgment and strategic
decisions of management and other personnel; and other factors referenced in
this Prospectus.

                   SPECIAL NOTE REGARDING CERTAIN TRANSACTIONS

         In January 1998, the Company entered into a definitive agreement to
acquire Infotel Technologies (Pte) Ltd ("Infotel"), a communications systems
integrator located in Singapore. Closing of the transaction is contingent upon
the Company obtaining the financing necessary to complete the acquisition. In
the event that the Company is unable to complete the transaction by June 24,
1998, the Company is obligated to pay to the Infotel stockholders a termination
fee in the amount of approximately $312,500, together with interest at 3% above
the prime rate. See "Recent Developments" for a more complete description of the
terms of the proposed acquisition. See also the audited and unaudited financial
statements of Infotel and the pro forma financial statements of the Company
included in this Prospectus in accordance with the rules and regulations
promulgated by the Securities and Exchange Commission. There is no assurance
that the pending acquisition of Infotel will be completed by the Company,
notwithstanding the inclusion in this Prospectus of the Company's pro forma
financial information and the audited and unaudited financial statements of
Infotel.

         In April 1998, the Company entered into a financing transaction with
certain of the Selling Stockholders pursuant to which the Company agreed to sell
shares of the Series A Convertible Preferred Stock of the Company that are
convertible into shares of the Common Stock offered hereby. The maximum
aggregate proceeds of the offering of Preferred Stock are $3.0 million, of which
$1,250,000 (less certain costs and expenses in the amount of approximately
$162,500) had been paid to the Company as of the date of the filing of the
Registration Statement on Form S-3 of which this Prospectus is a part. Payments
for additional installments of Preferred Stock are payable to the Company in
accordance with, and are subject to the terms of, the Preferred Stock financing.
See "Recent Developments" for a more complete description of the terms of the
Preferred Stock financing.

                               PROSPECTUS SUMMARY

         The following summary is qualified in its entirety by reference to the
more detailed information and financial statements, appearing elsewhere in or
incorporated by reference into this Prospectus. Each prospective investor is
urged to read this Prospectus in its entirety. This Prospectus includes certain
trademarks of NHancement and its subsidiaries.

                                   The Company

         NHancement Technologies Inc. is a multimedia communications systems
integrator, headquartered in Fremont, California. Its objective is to become a
leading global systems integrator of communications-centric products. The
Company, through its two operating subsidiaries, Voice Plus, Inc., a California
corporation ("Voice Plus" or "VPI"), also headquartered in Fremont, California,
and Advantis Network & System Sdn Bhd, a Malaysian corporation headquartered in
Kuala Lumpur ("Advantis"), provides businesses with communications products and
technological innovations designed to enhance efficiency. Services currently
provided by the Company include voice messaging, e-mail, paging and multimedia
systems, network servers, local area networks, wide area networks, routers,
transmission systems and network security systems.

         The Company was incorporated in 1996 to pursue a business combination
opportunity with Voice Plus(R), a company engaged in the business of integrating
voice processing systems with telecommunications equipment, and BioFactors, Inc.
("BioFactors" or "BFI"), a development stage company incorporated in Delaware
that offered the FACTOR 1000(R) system, a proprietary computerized human
impairment testing system. These two companies were acquired by NHancement on
February 3, 1997 pursuant to two separate merger transactions whereby each of
Voice Plus and BioFactors became wholly-owned subsidiaries of the Company.
Immediately following these acquisitions, the Company completed an initial
public offering ("IPO") of shares of its Common Stock.

         Subsequent to the completion of the IPO, management decided to combine
the operations of Voice Plus and BioFactors into a single entity. Effective as
of November 12, 1997, BioFactors was merged with and into Voice Plus in a
statutory merger intended to qualify, for federal income tax purposes, as a
reorganization under Section 368 of the Internal Revenue Code of 1986, as
amended. Voice Plus was the surviving corporation in the merger transaction with
BioFactors, and the separate existence of BioFactors ceased on the effective
date of the merger. The operations of the combined entity are currently being
conducted under the name of "Voice Plus."

         Prior to its merger with Voice Plus, BioFactors had concentrated on
developing a market for the FACTOR 1000 system, which is used for detecting
worker impairment. The Company has since determined that such effort is no
longer justified, given the resources required to develop such a market, as well
as the need to dedicate its financial resources to its other core businesses,
and plans to seek a buyer for the Factor 1000 technology in 1998.

         The acquisition of Advantis was completed by the Company on December
15, 1997. Advantis, now a wholly-owned subsidiary of NHancement, is a
communications systems integrator formed to address the growing communications
infrastructure needs of Malaysia.

         On January 16, 1998, the Company entered into a definitive agreement to
acquire all of the issued and outstanding shares of the capital stock of Infotel
Technologies (Pte) Ltd ("Infotel"), a company organized under the laws of
Singapore. The terms of the agreement require a cash payment of approximately
$2.3 million, notes payable by NHancement to the Infotel stockholders of
approximately $2.0 million (with payment subject to Infotel achieving certain
1998 and 1999 profitability targets), and the issuance of 431,000 shares of
NHancement Common Stock. Consummation of the transaction is contingent upon the
Company obtaining the financing necessary to complete the acquisition, the
closing of which must occur, if at all, by no later than June 24, 1998.

         The Company recently entered into a securities purchase agreement
providing for the sale to certain of the Selling Stockholders of shares of
Series A Convertible Preferred Stock, all or a portion of the proceeds of which
will be applied toward the purchase price of Infotel. The maximum aggregate
amount of the Preferred 


                                       4
<PAGE>   8

Stock financing is $3.0 million, of which $1,250,000 (less certain costs and
expenses in the amount of approximately $162,500) had been paid to the Company
as of the date of the filing of the Registration Statement on Form S-3 of which
this Prospectus is a part; and additional installments are payable to the
Company provided certain conditions are satisfied (see "Recent Developments" for
a more complete description of the terms of the Preferred Stock financing).
Should the Infotel acquisition be consummated, in addition to the Company's
existing portfolio of infrastructure communications equipment products, it will
provide radar system integration, turnkey project management services and test
instrumentation, as well as a wider portfolio of communications equipment. There
is no assurance that the Company will be able to consummate the Infotel
transaction or to obtain the financing necessary to complete the Infotel
acquisition. For a more complete description of the terms of the Infotel
transaction and the Series A Convertible Preferred Stock offering, as well as
the shares of Common Stock being offered hereby, see "Selling Stockholders" and

Nasdaq Symbol                               Common Stock "NHAN."

- --------------------

(1) Estimated based in part on the aggregate number of shares of Common Stock
that may be issued upon conversion of shares of Series A Convertible Preferred
Stock issued or issuable to the Selling Stockholders, based on a conversion
price equal to 75% of the average closing bid price of the Common Stock for the
five (5) trading days ending on May 12, 1998. A greater or lesser number of
shares of Common Stock may be offered hereby in the event that (i) certain of
the Selling Stockholders do not acquire the maximum aggregate number of shares
of Preferred Stock that are convertible into the Common Stock offered hereby;
(ii) certain of the Selling Stockholders convert less than all shares of
Preferred Stock held by such Selling Stockholders into shares of Common Stock;
or 



                                       5
<PAGE>   9

(iii) the conversion price of the Preferred Stock is more or less than the
conversion price in effect on or about May 12, 1998. Any increase in the number
of shares issuable upon conversion of the Series A Convertible Preferred Stock
by reason of the floating rate conversion price, issuable as a result of accrued
but unpaid dividends on the Series A Convertible Preferred Stock, or issuable by
operation of certain antidilution provisions, automatically will result in an
increase in the number of shares covered by the Registration Statement on Form
S-3 of which this Prospectus is a part. Number of shares also includes 150,000
shares offered for sale hereby James Gillespie, an affiliate of the Company. See
"Risk Factors," "Selling Stockholders" and "Recent Developments."

(2) Based on actual shares of Common Stock outstanding on the date of this
Prospectus. Does not include (i) shares of Common Stock issuable upon conversion
of the Preferred Stock outstanding on the date of this Prospectus; (ii) shares
of Common Stock issuable to the former stockholders of Advantis upon
satisfaction of certain conditions precedent to issuance of such shares; (iii)
shares of Common Stock issuable to the current stockholders of Infotel, if, and
in the event that, the Company acquires Infotel; (iv) outstanding options and
options available for grant under the Company's Equity Incentive Plan, as
amended through the date of this Prospectus; or (v) other outstanding options or
warrants.

(3) Assumes issuance of all shares of Series A Convertible Preferred Stock and
conversion of all such shares into Common Stock at the conversion rate described
in Footnote 1 above. The actual number of shares of Common Stock outstanding may
be more or less, as described in Footnote 1 above. Does not include exercise of
any outstanding options, warrants or other convertible securities.

                                  RISK FACTORS

         An investment in the shares of Common Stock offered hereby involves a
high degree of risk relating to the Company, the markets in which the Company
operates and the securities markets, particularly the markets for securities of
smaller issuers such as the Company. Prospective purchasers of Common Stock
should consider carefully the information set forth below, as well as the other
information in this Prospectus, in determining whether to purchase the shares of
Common Stock offered hereby.

         In addition to the other information contained in this Prospectus, the
following risk factors should be considered carefully before purchasing the
Common Stock offered hereby. The discussion in this Prospectus, and in the
Company's annual, quarterly and other periodic reports incorporated in this
Prospectus, contains forward-looking statements that involve risks and
uncertainties. Such forward-looking statements involve known and unknown risks,
uncertainties and other factors which may cause the actual results, performance
or achievements of the Company, or industry results, to be materially different
from any future results, performance or achievements expressed or implied by
such forward-looking statements. See "Special Note Regarding Forward-Looking
Statements" on page ____. Such factors include, among others, the risk factors
set forth below.

Risks Associated with Delisting of Common Stock; Penny Stock Rules.

         Although the Common Stock was approved for quotation on the Nasdaq
SmallCap Market System in connection with the Company's IPO, there can be no
assurance that it will remain eligible to be included on the Nasdaq SmallCap
Market System. In this regard, on or about April 16, 1998, Nasdaq informed the
Company that it no longer met the requirements for continued listing on the
Nasdaq SmallCap Market System. Specifically, the Company failed to meet the
requirements of Nasdaq Marketplace Rule 4310(c)(2) which requires that an issuer
maintain (i) net tangible assets of Two Million Dollars ($2,000,000); (ii)
market capitalization of Thirty-Five Million Dollars ($35,000,000); or (iii) net
income of Five Hundred Thousand Dollars ($500,000) in the most recently
completed fiscal year or in two of the last three most recently completed fiscal
years. The Company has notified Nasdaq of the steps it has taken and proposes to
take in order to remedy the above deficiency. The propriety of continuing the
Company's listing on the Nasdaq SmallCap Market System is currently being
reviewed by Nasdaq. While the Company believes that it will be in position to
meet these listing requirements in the near-term future, such belief is
dependent in part upon the Company completing the Infotel acquisition, the
financing for which had not been completed as of the date of this Prospectus.
There can be no assurance that the Company will in fact meet these requirements
in any future period.

         If the Company is otherwise unable to meet the Nasdaq SmallCap Market
System's continuing listing requirements described above, Nasdaq may take
appropriate action against the Company, including placing 



                                       6
<PAGE>   10

restrictions on or additional requirements for listing of its Common Stock or
the denial of listing of its Common Stock. If the Company's Common Stock is
delisted from the Nasdaq SmallCap Market System, the Company will become subject
to the Securities and Exchange Commission's "penny stock" rules, and as a
result, an investor will find it more difficult to dispose of, or to obtain
accurate quotations as to the price of, the Company's Common Stock.

         The "penny stock" rules under the Exchange Act impose additional sales
practice and market-making requirements on broker-dealers who sell and/or make a
market in such securities. For transactions covered by the penny stock rules, a
broker-dealer must make special suitability determinations for purchasers and
must have received the purchaser's written consent to the transaction prior to
sale. In addition, for any transaction involving a penny stock, unless exempt,
the rules require delivery prior to any transaction in a penny stock of a
disclosure schedule prepared by the Commission relating to the penny stock
market. Disclosure is also required to be made about commissions payable to both
the broker-dealer and the registered representative and current quotations for
the securities. Finally, monthly statements are required to be sent disclosing
recent price information for the penny stock held in the account and information
on the limited market and penny stocks. As a result, the Company's delisting
from the Nasdaq SmallCap Market System and its becoming subject to the rules on
penny stocks would negatively affect the ability or willingness of
broker-dealers to sell or make a market in the Company's securities and,
therefore, would severely and adversely affect the market liquidity for the
Company's Common Stock.

Prior Losses; Uncertainty of Future Profitability.

         For the year ended December 31, 1997, the Company incurred a net loss
in the amount of $4.6 million on net revenues of $9.0 million. The loss resulted
primarily from a combined charge of a $4.7 million impairment write-off and
amortization of goodwill associated with the Company's acquisition of Voice Plus
in February 1997. Net revenues for the first quarter of 1998 were $1.22 million
with a net loss for the quarter of approximately $786,300. VPI revenues were
significantly below historical levels for the same period in 1997, due in part
to the uncertainty surrounding the sale of the customer premises equipment
business of Centigram Communications Corporation, which management of the
Company believes caused VPI customers to delay their buying decisions. In
addition, the weakness of the Malaysian currency caused Advantis customers to
delay implementation of planned projects. Also, the issuance of the Series A
Convertible Preferred Stock that is convertible into shares of Common Stock at a
25% discount of which will be reflected as a preferred stock dividend, will
result in an increase in the loss applicable to Common Stock in computing the
net loss per share.

         The failure of the Company to produce positive operating results may
affect the future value of the Common Stock sold hereunder, may contribute to
the Company losing its eligibility for listing of the Common Stock on the Nasdaq
SmallCap Market System, may adversely affect the Company's ability to obtain
debt or equity financing on terms acceptable to the Company, and may prevent the
Company from completing future acquisitions, including the Infotel acquisition.
See generally "Risk Factors -- Possible Volatility of Stock Prices," "-- Risks
Associated with Delisting of Common Stock; Penny Stock Rules," "-- Financing
Risks," and other risks described under "Risk Factors," as well as "Recent
Developments."

Possible Volatility of Stock Prices.

         The over-the-counter markets for securities such as the Common Stock
historically have experienced extreme price and volume fluctuations during
certain periods. These broad market fluctuations and other factors, such as new
product developments and trends in the Company's industry and the investment
markets generally, as well as economic conditions and quarterly variations in
the Company's results of operations, may adversely affect the market price of
the Common Stock. In addition, there can be no assurance that the Company's
Common Stock will remain eligible for listing on the Nasdaq SmallCap Market
System. See "Risk Factors--Risks Associated with Delisting of Common Stock;
Penny Stock Rules."

Financing Risks.

         The acquisition of complementary businesses and products is an element
of the Company's business strategy. If a cash payment in excess of available
working capital is required to make an acquisition, the 



                                       7
<PAGE>   11

Company will need to obtain additional debt or equity financing. Debt financing
may require the Company to pay significant amounts as interest and principal
payments, thus reducing the resources available to expand its existing
businesses. Equity financing may be dilutive to the Company's existing
stockholders' interest in the assets or earnings of the Company. There can be no
assurance that the Company will be able to obtain either debt or equity
financing if and when it is needed for acquisitions or that, if available, such
financing will be available on terms the Company deems acceptable. The inability
of the Company to obtain such financing would have a material adverse effect on
the Company's acquisition strategy. Further, the refusal of potential
acquisition candidates to accept Common Stock in payment of the Company's
purchase price obligations, in whole or in part, could require the Company to
reduce or curtail its acquisition strategy. To the extent that Common Stock is
used as consideration in an acquisition transaction, such stock issuance may be
dilutive to the Company's existing stockholders. Even if the Company is able to
obtain financing needed for an acquisition, the terms of such financing may
involve considerable costs to the Company.

VPI's Strategic Relationship with Centigram Communications Corporation.

         VPI's business is based upon the integration of hardware and software
and telecommunications and data processing equipment manufactured by others into
integrated systems designed to meet the needs of its customers. Although VPI has
distributor agreements with a number of equipment manufacturers, substantially
all of its revenue is based upon products manufactured by Centigram
Communications Corporation ("Centigram"). The Company depends upon Centigram to
offer products that are competitive with products offered by other manufacturers
as to technological advancement, reliability and price. If Centigram's
competitors should surpass Centigram in any of these qualities, the Company may
be required to establish alternative strategic relationships. Any such
development, or any other adverse change in the Company's distributor
relationship with Centigram, would adversely affect the Company's business for
an indeterminate period of time until new supplier relationships could be
established. In this regard, Centigram recently announced to the public the sale
to Mitel Corporation ("Mitel") of its customer premises equipment ("CPE")
business. The distributor agreement entered into with Centigram may be canceled
by either party upon ninety (90) days' notice and is subject to termination in
the event that the Company defaults on or is otherwise in breach of various of
its obligations under the agreement. The Company has begun negotiations with
Mitel to insure that its access to Centigram products will continue
uninterrupted. Mitel has indicated its intention to maintain the Centigram CPE
distribution, including the VPI distributor agreement. However, an agreement has
not yet been signed with Mitel and no assurances can be made that an agreement
with terms acceptable to the Company will be successfully consummated. If Mitel
does not permit third parties such as the Company to continue to distribute the
CPE products, there would be a significant adverse impact upon the Company's
business for an indeterminate period of time until new supplier relationships
could be established.

Reliance upon VPI's and Advantis' Distributor and Supplier Relationships;
Dependence on Significant Customers.

         VPI has distributor agreements with a number of equipment manufacturers
in addition to Centigram. Also, Advantis has distributor agreements with a
number of equipment manufacturers. In accordance with the terms of these
distributor agreements, a manufacturer may discontinue the distributor
relationship because of factors related to a particular distributor or because
of a manufacturer's decision to change its method of distributing its products
to all or parts of its markets. In making such a change, a manufacturer of key
products sold by a distributor may effectively become a direct competitor of its
former distributor. Moreover, a manufacturer may reduce its dealer discounts,
eliminate any exclusive distribution rights, and/or reduce the manufacturer's
support of a distributor or otherwise adversely affect the competitive
environment in which the distributor sells the manufacturer's products. Any
material change in VPI's or Advantis' distributor relationships with their key
suppliers or any interruption of the delivery of equipment to VPI or Advantis by
any of their key suppliers would have a material adverse effect upon the
Company.

         For the fiscal year ended December 31, 1997, revenues from sales to two
of the Company's customers accounted for approximately 19% and 7% of the total
net revenues for the year. The loss of one or more significant customers of the
Company would have a material adverse effect upon the Company's financial
condition. In addition, while Infotel's business is diversified over several
business segments and customer groups, its systems and networking business is
characterized by very large contracts and projects directed at a 



                                       8
<PAGE>   12

limited number of customers in any one period. The loss or rescheduling of one
or more such contracts would affect the timing of Infotel's revenues and cash
flow, and, if Infotel is acquired by the Company, could result in a material
adverse effect upon the Company's financial condition.

Competition in VPI's Voice Processing and Customer Premises Equipment
Businesses.

         The voice processing and customer premises equipment markets are highly
competitive and competition in this industry is expected to intensify with the
introduction of new product enhancements and new competitors. VPI competes with
a number of larger integrated companies that provide competitive voice
processing products and services as subsets of larger product offerings,
including all the former regional Bell operating companies and major PBX
equipment manufacturers, such as Fujitsu Limited and Lucent Technologies Inc.
("Lucent"), formerly a division of AT&T. These integrated public company
competitors are substantially larger than the Company and have substantially
greater revenues than the Company, and, as a result, may encroach on the
Company's voice processing equipment and service markets. Additionally, in the
customer premises equipment markets, VPI competes with two types of equipment
companies: (i) interconnects (PBX providers), including Lucent, Northern Telecom
Limited, Fujitsu Limited and NEC Corporation, and (ii) independent voice
processing manufacturers, such as Octel Communications Corporation (now owned by
Lucent), Digital Sound Corporation, Active Voice Corporation, Applied Voice
Technology, Inc., Glenayre Technologies, Inc. and Comverse Technology, Inc.,
among others, also compete with the Company in the service provider market.
VPI's competitors have better name recognition in the market, a larger installed
base of customers and greater financial, marketing and technical resources than
the Company.

Competition in Advantis' and Infotel's Infrastructure Communications Equipment
Businesses.

         The infrastructure communications market in Malaysia is largely driven
by the growth of the country's manufacturing and industrial sectors as well as
the country's urbanization. Consequently, much of the market opportunity is
controlled by either the government or the general construction contractors.
Both market sectors are addressed by several local Malaysian companies that are
larger than Advantis. In addition, while Advantis currently does not compete
directly with other large systems integrators in the market, since it acts as a
sub-contractor to another larger systems integrator with whom it has aligned
itself, the Company expects that Advantis will face such competitors directly in
the future when it has better established its installed base. Further, continued
growth of Malaysia's manufacturing and industrial sectors will likely fuel
competition in the country's infrastructure communications market.

         Infotel competes against several large companies in Singapore that are
better capitalized. Although Infotel has in the past managed to compete
successfully against such larger companies on the basis of its engineering and
project management expertise, there can be no assurance that such expertise will
permit Infotel to compete effectively with such larger companies in the future.
Further, various large manufacturers have established their own branch offices
in Singapore and compete against Infotel.

Risks in Integrating Acquired Companies.

         Acquisitions may involve a number of special risks, including adverse
short-term effects on the Company's operating results, diversion of management's
attention from the operations of the Company, dependence on retention, hiring
and training of key personnel, risks associated with unanticipated problems or
legal liabilities and amortization of acquired intangible assets, some or all of
which could have a material adverse effect on the Company's operations and
financial performance. Successfully integrating the operations of additional
companies into those of the Company will require the cooperative efforts of the
managers and employees of the respective business entities, including the
integration of the owners or managers of smaller companies into roles that
require them to report to supervisors. Significant costs and management time may
be required to integrate management control systems. Furthermore, to manage its
growth effectively, the Company must continue to improve its operational,
financial and management controls and information systems, to accurately
forecast sales demand, to control its overhead and to manage its marketing
programs. There can be no assurance of accomplishing these results without
encountering substantial costs, delays or other problems. In this regard, the
Company experienced a net loss of $4.6 million on revenues of $9.0 million for
the fiscal year ended December 31, 1997, primarily due to a combined charge of a
$4.7 million impairment write-off and amortization 



                                       9
<PAGE>   13

of goodwill associated with the Company's acquisition of Voice Plus in February
1997. Other acquisitions, such as the recently completed acquisition of Advantis
or the pending acquisition of Infotel, if consummated, may result in impairment
charges in the future. See "Risk Factors -- Prior Losses; Uncertainty of Future
Profitability." Accordingly, no assurance can be given that the future
performance of the Company's subsidiaries will be commensurate with the
consideration paid to acquire such companies. If management fails to establish
the needed controls and to manage growth effectively, the Company's operating
results, cash flows and overall financial condition will be adversely affected.

Pro Forma Financial Statements

         This Prospectus incorporates by reference certain historical financial
statements of the Company and contains pro forma financial statements. The pro
forma financial statements reflect the Company's best estimate of the impact of
the Infotel acquisition on the historical financial statements of the Company.
Since the acquisition of Infotel has not closed, the actual impact of the
transaction on the Company's future financial statements could be materially
different than as presented.

Foreign Market and Currency Risks.

         The Company's global business strategy subjects it to foreign market
and currency risks. In particular, the devaluation of the Malaysian currency
(Ringgit) in relation to the United States Dollar has affected the short and
medium term revenues of the Company's Advantis subsidiary in Malaysia. Although
the Company believes that the long term effects of the currency problems in
Malaysia and the Asian region will be manageable, the short term uncertainty
related to fluctuations in the Ringgit has caused Advantis' customers to
postpone the deployment of communications equipment. In addition to the short
term effects of the Ringgit devaluation described above, which weakened
substantially in 1997, any prolonged devaluation of the Ringgit can be expected
to materially and adversely affect the operations and financial condition of
Advantis, and may result in a material adverse effect on the business and
financial condition of the Company. The revenue performance of Advantis in the
first calendar quarter of 1998 was significantly below historical levels and
this trend is expected to continue through 1998, as customers defer purchases
due to the weakness of the Malaysian currency. The Company's proposed
acquisition of Infotel may also subject the Company to foreign market and
currency risks in Singapore.

Risks Associated with Future Unspecified Acquisitions.

         With the exception of the proposed acquisition of Infotel, the Company
has not entered into any agreements, understandings or arrangements with respect
to any future acquisitions, although it is pursuing various acquisition
opportunities. The Company does not intend to submit a proposed acquisition or
other business transaction to the review and vote of its stockholders, except as
required by Delaware law. Even if submitted to a vote of stockholders, the
Company's management and non-management directors own a substantial portion of
the Company's outstanding voting securities and may be able to control the
outcome of any such proposal. The Company's growth strategy is highly dependent
on the Company's ability to make future acquisitions.

Subordination of Claims of Stockholders.

         The Company is a holding company and its assets consist of its
investments in its subsidiaries, namely VPI and Advantis, and, if the proposed
acquisition of Infotel is consummated, Infotel. The Company's rights, and,
therefore, the extent to which holders of Common Stock will be able to
participate in the distribution of assets of any subsidiary upon such
subsidiary's liquidation or reorganization, will be subject to prior claims of
the subsidiary's creditors, including trade creditors, except to the extent that
the Company may itself be a creditor with recognized claims against such
subsidiary (in which case the claims of the Company would still be subject to
the prior claims of any secured creditor of such subsidiary and of any holder of
more senior indebtedness).

Dependence Upon Key Personnel.

         The Company believes its success will depend to a significant extent on
the efforts and abilities of certain of its and its subsidiaries' senior
management, in particular, those of Esmond T. Goei, the Company's Chairman 



                                       10
<PAGE>   14

of the Board of Directors, Chief Executive Officer and President, and Douglas S.
Zorn, the Company's Executive Vice President, Chief Financial Officer and
Treasurer, who is also a director of the Company. The Company has purchased key
personnel insurance policies in the amount of $1.0 million on the lives of each
of Messrs. Goei and Zorn, which policies name the Company as the sole
beneficiary. The Company intends to purchase additional key personnel insurance
policies on other key employees. There can be no assurance that the Company will
be able to maintain existing key personnel insurance policies or obtain key
personnel insurance policies on additional individuals at an acceptable cost.
The loss of the services of any of the Company's key employees would have a
material adverse effect on the Company.

Risks Related to Intellectual Property.

         The Company intends to protect vigorously the Company's intellectual
property against infringement or misappropriation by others. There can be no
assurance, however, that steps taken by the Company will prevent
misappropriation of its intellectual property or that competitors will not
develop products similar to the Company's products. Further, the enforcement of
proprietary rights of the Company through litigation could result in costs to
the Company that could have a material adverse effect on its financial
condition. In addition, although the Company believes that its intellectual
property, including its CTT and FACTOR 1000(R) technology, does not infringe on
the proprietary rights of third parties, there can be no assurance that
infringement or invalidity claims will not be asserted against the Company in
the future. An adverse determination or the costs of defending litigation based
on such claims could have a material adverse effect on the Company's business
and financial condition.

Product Liability Exposure; Litigation Risk; Limited Insurance.

         The Company's human impairment testing business, which it plans to
dispose of in 1998, exposes it to potential litigation by employees of companies
using FACTOR 1000(R) testing if the employee's employment relationship is
affected thereby. Product and service liability insurance is expensive, to the
extent it is available at all. The Company currently maintains general liability
insurance, including products liability insurance, in the amount of $2.0 million
per occurrence and $2.0 million in the aggregate per policy year. There can be
no assurance, however, that the Company will be able to maintain such insurance
on acceptable terms, that the Company will be able to secure increased coverage
if needed or that any insurance policy will provide adequate protection against
successful claims. A successful claim brought against the Company in excess of
the Company's insurance coverage could have a material adverse effect upon the
Company.

Governmental Regulation.

         The Telecommunications Act of 1996 eliminated government mandated
barriers between local and long distance calling, cable television, broadcasting
and wireless service/service providers. Consequently, local telephone companies,
the traditional long distance carriers and cable television companies may now
provide both local telephone and long distance service, as well as television
programming. Such increased competition likely will change the infrastructure
for implementing communications applications, such as voice and electronic
messaging. Such changes could have a material adverse impact on VPI's voice
processing business.

         The acquisition of Advantis required the approval of the Foreign
Investment Committee of the Malaysian government, which approval was obtained
subject to the Company agreeing to apply for certification as a Multimedia Super
Corridor ("MSC") company in Malaysia, although no time limit was specified for
obtaining such certification. The MSC is an economic development zone
established by the Malaysian government to stimulate the indigenous development
of information technology. To encourage the participation of businesses in the
zone, MSC status provides certain corporate benefits including access to
government grants, preferred vendor status within the MSC and tax-free status
for ten years. MSC status is dependent on an applicant's contribution to the
betterment of the Malaysian people through the application of certain technology
of which communications technology is a prime component. The Company has
undertaken certain efforts to obtain MSC certification, including the hiring of
a consultant knowledgeable in such processes. The Company believes that it has
the necessary merits for certification, but there is no assurance that the
Company will be able to obtain such certification.

Shares Eligible for Future Sale.

         The market price for the Common Stock could be adversely affected by
the availability of shares of Common Stock for sale or actual sales of
substantial amounts of Common Stock by existing or future stockholders. At April
30, 1998, approximately 3,406,825 shares of Common Stock were freely tradeable
without restriction or further registration under the Securities Act, by persons
other than "affiliates" of the Company. Upon registration of the shares offered
for sale hereby, and receipt of certain approvals required to be obtained by the
Company in connection with the Series A Convertible Preferred Stock offering, a
minimum of an additional 1,638,375 shares will be available for sale on the open
market, subject to restrictions on transfer affecting sales of securities held
by affiliates. The actual number of shares offered for sale hereby may, in fact,
be significantly greater since the Company is obligated to issue a currently
indeterminate number of shares of Common Stock upon conversion of the Series A
Convertible Preferred Stock. The exact number of shares of Common Stock issuable
pursuant to such conversion cannot be estimated with certainty because,
generally, such issuances of Common Stock will vary inversely with the market
price of the Common Stock at the time of such conversion. The Series A
Convertible Preferred Stock is also subject to various adjustments to prevent
dilution resulting from stock splits, stock dividends or similar transactions,
and additional shares of Common Stock are issuable as a result of accrued but
unpaid dividends.

         Approximately 821,175 shares of Common Stock are "restricted
securities" within the meaning of Rule 144 under the Securities Act ("Rule 144")
and may not be sold in the absence of registration under the Securities Act
unless an exemption from registration is available, including the exemption
afforded by Rule 144. Any Common Stock issued in the future to the former
stockholders of Advantis, pursuant to the terms of the Advantis acquisition
agreement, and any Common Stock issued to the stockholders of Infotel, in the
event that the Infotel transaction is consummated, will be "restricted
securities" within the meaning of Rule 144. The holders of approximately
1,029,675 shares of Common Stock (in addition to the shares offered hereby)
possess registration rights with respect to such shares. In addition, following
the expiration in August 4, 1998 of certain lock-up agreements restricting the
transfer of certain of the shares held by the Company's Chairman of the Board
and Chief Executive Officer and affiliates and other officers, directors and key
employees, approximately 410,588 shares of Common Stock will become available
for resale in the public market, subject to the volume limitations, holding
periods and other restrictions of Rule 144 affecting the transfer of such
shares. At April 30, 1998, 1,476,500 shares of Common Stock had been reserved
for issuance under the Company's Equity Incentive Plan, as amended to date. The
Company also has granted warrants to third parties to purchase 846,796 shares of
Common Stock at prices ranging from $4.80 to $188.80, together with certain
registration rights relating to certain of such shares. Future sales of shares
of Common Stock, or the perception that such sales could occur, could have a
material adverse effect on the market price of the Common Stock.

No Dividends.

         To date, the Company has not paid any cash dividends on its Common
Stock and does not expect to declare or pay any cash or other dividends in the
foreseeable future. In addition, the Preferred Stock financing documents
restrict the Company from paying dividends on its Common Stock.

Control by Management.

         The Company's current officers and directors own over 25% of the issued
and outstanding shares of Common Stock and, thus, may be able to influence the
election of a majority of the Company's directors and thereby direct the
policies of the Company.

Anti-Takeover Provisions.

         Certain provisions of the Company's Amended and Restated Certificate of
Incorporation, as amended to date (the "Certificate of Incorporation"), and
certain provisions of the Delaware General Corporation Law may make it difficult
to change control of the Company. For example, the Certificate of Incorporation
permits the Board of Directors, without stockholder approval, to issue one or
more classes or series of Preferred Stock having the number of shares,
designations, relative voting rights, dividend rates, liquidation and other
powers, rights, 



                                       12
<PAGE>   16

preferences and limitations that the Board of Directors establishes. The
issuance of Preferred Stock, including the Series A Convertible Preferred Stock
described in this Prospectus, while providing flexibility in connection with
possible financings, acquisitions and other corporate purposes, could, among
other things, adversely affect the voting power of the holders of Common Stock.
In addition, under certain circumstances, the issuance by the Company of
Preferred Stock, including the Series A Convertible Preferred Stock, the shares
of which are convertible into the Common Stock offered hereby and described
herein, may make it more difficult for a third party to gain control of the
Company, may discourage bids for the Common Stock at a premium and may otherwise
adversely affect the market price of the Common Stock. Employment agreements
with the Company's Chief Executive Officer and Chief Financial Officer provide
for substantial severance pay in the event of a "Change of Control" of the
Company, as such term is defined in such agreements. In addition, in the event
of a change of control of the Company, certain outstanding stock options will
vest and become immediately exercisable and certain restricted stock awards will
become nonforfeitable.

Conflicts of Interest.

         Certain officers, directors and stockholders of the Company have
entered into loan transactions with the Company, have purchased and sold
securities of the Company and have engaged or may engage in other businesses for
their own account, which may be in competition with the Company, all of which
could give rise to conflicts of interest. The Company does not intend to enter
into business transactions or arrangements with officers, directors or
stockholders unless they are on terms at least as favorable to the Company as
could be obtained from unrelated third parties. However, there can be no
assurance that any transaction or arrangement between the Company and an
officer, director or stockholder will be advantageous to the Company, that
conflicts of interest will not arise with respect to such transactions or
arrangements, or that if such conflicts arise, they will be resolved in a manner
favorable to the Company.

Indemnification of Directors and Officers by the Company; Limitations on
Liability.

         The Certificate of Incorporation limits the liability of directors of
the Company for monetary damages for breaches of directors' fiduciary duty of
care. In addition, the Delaware General Corporation Law and the Certificate of
Incorporation contain provisions for indemnification of officers and directors
of the Company. The Certificate of Incorporation requires the Company to
indemnify such persons to the full extent permitted by Delaware law. Each
officer and director will be indemnified in any proceeding alleging breaches of
fiduciary duty to the Company and similar wrongful conduct if he or she acted in
good faith and in a manner which he or she reasonably believed to be in, or not
opposed to, the best interests of the Company. Indemnification would cover
expenses, including attorneys' fees, judgments, fines and amounts paid in
settlement.

         The Company's Bylaws also provide that the Board of Directors may cause
the Company to purchase and maintain insurance on behalf of any present or past
director, officer, employee, fiduciary or agent of the Company insuring against
any liability asserted against such person arising out of such person's
position, whether or not the Company would have the power to indemnify such
person. The Company currently maintains director and officer liability insurance
of $5.0 million per occurrence and $5.0 million in the aggregate per policy
year.

Year 2000 Potential Impact.

         The Company has begun to conduct a review of its internal computer
systems to identify the systems that could be affected by the "Year 2000" issue
and is developing an implementation plan to resolve any such problems. The Year
2000 problem is the result of computer programs being written using two digits
(rather than four) to define the applicable year. Software programs that have
time-sensitive software may recognize a date using "00" as the year 1900 rather
than the year 2000. This could result in a major system failure or
miscalculations. The Company presently believes that, with modifications to or
replacement of existing software, the Year 2000 problems will not pose
significant operational problems for the Company's domestic computer systems.
The Company believes that the costs associated with any such upgrade or
replacement of software will not be material, and that all such changes will be
implemented by the end of calendar year 1998. However, if such modifications are
not made in a timely manner, or are not made properly, the Company may be unable
to implement appropriate Year 2000 solutions, which could have a material
adverse effect on the Company's business, financial condition, results of
operations and cash flows.




                                       13
<PAGE>   17

         The Company distributes products from third party product equipment
manufacturers, some of which are susceptible to Year 2000 problems. During
fiscal year 1997, the Company initiated a review of the products its domestic
subsidiary, VPI, distributes to determine which, if any, are not capable of
recognizing the year 2000. Communications were initiated with all of the
manufacturers of such products to determine the nature and extent of any Year
2000 problems. Where potential computer problems of the Year 2000 products used
or distributed by the Company have been identified, these manufacturers have
stated that they have committed resources to resolving such problems prior to
year 2000. However, there can be no assurance that these manufacturers will, in
fact, timely complete the resolution of their Year 2000 problems or, even if
timely completed, that those solutions will be acceptable in the marketplace.
The solution to be provided by some manufacturers will involve a significant
upgrade cost to the end user, which may give rise to disputes and/or litigation
between the end user and the manufacturer, which may also involve the Company.
The costs of such possible disputes or litigation could be significant, thereby
resulting in a material adverse effect on the Company's business, financial
condition, results of operations and cash flows.

         The Company acquired Advantis Network & Systems Sdn Bhd, a Malaysian
company, on December 15, 1997. Additionally, the Company signed a definitive
agreement on January 16, 1998, to acquire Infotel Technologies (Pte) Ltd
("Infotel"), a company organized under the laws of Singapore. The Company has
begun, but has not yet completed, its review of the internal computer systems of
Advantis and Infotel to identify the systems in each company that are not Year
2000 compliant; thus, at this time the Company has not been able to determine
whether Year 2000 problems (if any) will pose a significant operational problem
for the computer systems of either of those two companies, and whether those
operational problems, if any, would result in a material adverse effect on the
Company's business, financial condition or results of operations. Similarly, the
Company has not yet begun its review of third-party products distributed by
Advantis or Infotel to determine the nature and extent of Year 2000 problems, if
any, with such products. As a result, the Company is currently unable to
determine whether there are any Year 2000 problems associated with such
third-party products, and if so, whether the manufacturers will be able to
timely resolve any such problems. The Company also has not been able to
determine whether the legal systems of Malaysia and Singapore would result in
more or less litigation exposure to the Company and its subsidiaries if there
are disputes between the end user of a product installed by either Advantis or
Infotel, and the manufacturer.

                               RECENT DEVELOPMENTS

         On January 16, 1998, the Company entered into a definitive agreement to
acquire all of the issued and outstanding shares of the capital stock of Infotel
Technologies (Pte) Ltd ("Infotel"), a company organized under the laws of
Singapore which provides radar system integration, turnkey project management
services, and test instrumentation, as well as a wide portfolio of
communications equipment. Consummation of the transaction is contingent upon the
Company obtaining third party financing on terms satisfactory to the Company by
no later than June 24, 1998. The extension of the closing date from April 1998
to June 1998 was agreed to by Infotel's stockholders, conditioned upon the
Company making certain concessions. These concessions included a deposit in
escrow of funds in the amount of approximately $937,500, approximately $312,500
of which, together with interest at the rate of 3% above the prime rate for the
period from April 14, 1998 through June 24, 1998, is payable to the Infotel
stockholders in the event that the transaction fails to close on or before June
24, 1998. The funds in escrow will be credited toward the purchase price in the
event that closing of the transaction occurs on or before June 24, 1998; any
interest earned on the escrowed funds is payable to the Infotel stockholders as
additional consideration. The basic terms of the acquisition agreement require
an initial cash payment of approximately $2.3 million, notes payable by
NHancement to the Infotel stockholders of approximately $2.0 million (with
payment subject to Infotel achieving certain 1998 and 1999 profitability
targets), and the issuance of 431,000 shares of NHancement's Common Stock,
subject to certain price protections. There is no assurance that this
transaction will close as scheduled or that the Company will be able to secure
the financing necessary to complete the acquisition.

         On April 13, 1998, the Company signed a $3.0 million Series A
Convertible Preferred Stock financing agreement. Under the terms of the
agreement, the Company had been paid $1,250,000 (less commissions and certain
other costs and expenses of approximately $162,500) as of the date of filing of
the Registration Statement on Form S-3 of which this Prospectus is a part; and,
subject to satisfaction of certain conditions specified in the 



                                       14
<PAGE>   18

stock purchase agreement documentation, will receive $500,000 sixty days after
the effective date of the Registration Statement, $500,000 thirty days
thereafter and the final $750,000 thirty days thereafter. The failure by the
Company to comply with certain of the provisions of the agreement may result in
the Company being assessed amounts payable to the Preferred Stock investors.
Further, the issuance of shares of Preferred Stock, convertible into shares of
Common Stock in excess of 20% of the issued and outstanding shares of Common
Stock of the Company, requires stockholder approval under applicable rules and
regulations promulgated by Nasdaq. The Company plans to seek such approval at a
special meeting of stockholders to be held in June 1998 or such later date as is
determined by the Board of Directors of the Company.

         The Preferred Stock bears a 5% cumulative dividend and has a
liquidation preference equal to the original purchase price plus cumulative but
unpaid dividends. If the Company's Common Stock trades for a thirty day average
below $2.00 or the average daily volume for a thirty day period falls below
20,000 shares, the investors are not required to fund any remaining portion of
the $3.0 million in excess of the first $1,250,000 investment. Further, if the
five day average closing bid price of the Company's Common Stock falls below
$2.00 per share, the Company has the option to redeem the Preferred Stock at
118% of the original purchase price plus cumulative but unpaid dividends. Any
shares of Preferred Stock tendered for conversion prior to delivery of the
Company's notice of redemption shall not be affected by the redemption notice
and shall be converted into shares of Common Stock. As to any shares with
respect to which such conversion rights have not been timely exercised, such
conversion rights shall terminate upon delivery by the Company of its notice of
redemption. The Preferred Stock is convertible into Common Stock at the lesser
of the five day average closing bid price as of the April 13, 1998 initial
closing date or 75% of the five day average closing bid price at the time of
each conversion.

         The Common Stock offered hereby by certain of the Selling Stockholders
is issuable upon conversion of the Preferred Stock. The Company intends to
utilize all or a portion of the proceeds of this financing to pay a portion of
the initial cash payment on the pending Infotel acquisition; the balance
remaining, if any, will be used to pay amounts owing to certain creditors of the
Company and for working capital.

         The Company's operations for the first quarter of 1998 resulted in
revenues of about $1.22 million with a net loss for the quarter of approximately
$786,000. VPI revenues were significantly below historical levels for the same
period in 1997, due in part to the uncertainty surrounding the sale of
Centigram's CPE business, which management of the Company believes caused
customers to delay their buying decisions. The Company believes that VPI
revenues will begin to improve by the third quarter of 1998. Advantis' revenues
were significantly below historical levels, primarily due to customers deferring
purchases due to the weakness of the Malaysian currency. The Company expects
this revenues trend to continue.

                                 USE OF PROCEEDS

         The proceeds from the sale of the shares offered hereby will be solely
for the account of the Selling Stockholders. Accordingly, the Company will not
receive any of the proceeds from the sale of shares by the Selling Stockholders.

                              SELLING STOCKHOLDERS

         Of the shares of Common Stock offered hereby, 1,488,375 shares may be
issued upon the conversion of the 30,000 shares of Series A Preferred
Convertible Stock issued or proposed to be issued to The Endeavour Capital Fund
S.A. and AMRO INTERNATIONAL S.A. in the securities purchase transaction entered
into with the Company on April 13, 1998. Such number of shares may be higher or
lower due to the floating rate conversion price at which the Series A
Convertible Preferred Stock is convertible into Common Stock and the other
factors described on the cover page of this Prospectus and under the heading
"Prospectus Summary--The Offering." Pursuant to the terms of the securities
purchase agreement, the Company has agreed to sell to such investors up to
30,000 shares of Series A Convertible Preferred Stock for $3.0 million, net of
certain costs and expenses in the amount of approximately $162,500 paid by the
Company to counsel and other advisors to the investors, as well as to certain
finders. In addition, the securities purchase agreement provides for certain
additional payments to be made by the Company to counsel for the investors in
connection with the Form S-3 Registration Statement of which this Prospectus is
a part. The shares of Preferred Stock issued or issuable to the investors
pursuant to the 



                                       15
<PAGE>   19

Preferred Stock purchase agreement have been and will be issued by the Company
in reliance upon the exemption afforded by Section 4(2) of the Securities Act
and/or Regulation D promulgated by the Commission thereunder. The issuance to
the investors of additional shares of Preferred Stock is contingent upon
satisfaction by the Company of the conditions described under "Recent
Developments" and the Company's obtaining stockholder approval of certain of
such issuances. The Endeavour Capital Fund S.A. and AMRO INTERNATIONAL S.A. are
headquartered in Jerusalem, Israel and Zurich, Switzerland, respectively.

         Up to an additional 150,000 shares are being offered hereby by James S.
Gillespie, the founder of Voice Plus and currently a director of the Company.
Until recently, Mr. Gillespie served as the President of Voice Plus and the Vice
President of Sales of the Company. The shares being offered hereby by Mr.
Gillespie are being registered pursuant to the terms of a registration rights
agreement entered into with Mr. Gillespie in connection with the Company's IPO
in February 1997.

         The following table sets forth, to the knowledge of the Company, the
number of shares of Common Stock and the percentage of the outstanding shares of
Common Stock beneficially owned by each Selling Stockholder, the number of
shares to be offered and sold by such Selling Stockholder, and the number of
shares and percentage of outstanding shares to be beneficially owned by such
Selling Stockholder after such offering and sale, assuming that all the shares
offered by such Selling Stockholder are in fact sold. Unless otherwise
indicated, each person has sole investment and voting power with respect to the
shares set forth in the following table. As of April 30, 1998, the Company had
4,436,500 shares of Common Stock issued and outstanding, and 12,500 shares of
Series A Convertible Preferred Stock issued and outstanding.

- --------------------

(1)    Includes shares of Common Stock issuable on conversion of shares of
       Series A Convertible Preferred Stock which can be purchased within sixty
       days of the date hereof (assuming a conversion rate based on 75% of the
       average closing bid price of the Common Stock for the five trading days
       ending on May 12, 1998).

(2)    Excludes any shares issuable to Advantis or Infotel, respectively, upon
       satisfaction of certain conditions precedent set forth in the Advantis
       stock purchase agreement and in the definitive Infotel stock purchase
       agreement (closing of the transaction of which has not yet occurred).

(3)    Assumes sale of all shares of Common Stock offered hereby by the Selling
       Stockholders.

(4)    Assumes issuance of an aggregate of 15,000 shares of Series A Preferred
       Convertible Stock and conversion of such shares into Common Stock based
       on the conversion rate described in footnote 1 above, which amount may be
       higher or lower depending upon the actual conversion rate in effect on
       the date of any conversion of Preferred Stock into Common Stock. The
       actual number of shares of Common Stock offered for sale may be higher or
       lower based on a number of factors that cannot be predicted by the
       Company at this time. These factors include issuances of additional
       shares of Common Stock as a result of accrued but unpaid dividends, as
       well as issuances of additional shares in the event of any future stock
       dividends, stock distributions, stock splits or similar capital
       readjustments. There are also limitations on the number of shares of
       Common Stock that may be offered for sale at any time. See the cover page
       of this Prospectus, "Prospectus Summary--The Offering" and "Recent
       Developments."

(5)    Includes shares of Common Stock issuable upon exercise of options,
       warrants and other securities which are exercisable by Mr. Gillespie
       within sixty days as of the date hereof. Excludes shares of Common Stock
       issuable upon exercise of options, warrants and other securities which
       are exercisable by persons other than the Selling Stockholders as of the
       date of this Prospectus.

                              PLAN OF DISTRIBUTION

         The shares may be offered and sold from time to time by the Selling
Stockholders. No Selling Stockholder is required to offer or sell any of its or
his shares. Any such sales may be made on the Nasdaq SmallCap Market System or
such other national securities exchange on which shares of Common Stock are then
listed, through negotiated transactions or otherwise at prices and at terms then
prevailing or at prices related to the then-current market price or in
negotiated transactions. The Selling Stockholders directly, or through agents
designated from time to time, or through underwriters, brokers or dealers also
to be designated, may sell the shares from time to time on terms to be
determined at the time of sale. Any such underwriters, brokers or dealers may
receive compensation in the form of commissions or otherwise in such amounts as
may be negotiated by them. As of the date of this Prospectus, no agreements had
been reached for the sale of the shares or the amount of any compensation to be
paid to underwriters, brokers or dealers in connection therewith.



                                       17
<PAGE>   21

         The Company will bear all expenses in connection with the registration
and sale of the shares, other than commissions, concessions or discounts to
underwriters, brokers or dealers and certain of the fees and expenses of counsel
and other advisors to the Selling Stockholders.

         The Company has agreed to indemnify the Selling Stockholders and the
Selling Stockholders have agreed to indemnify the Company, its officers,
directors, employees, agents and controlling persons from certain damages or
liabilities arising out of or based upon any untrue statement or alleged untrue
statement of any material fact contained in or material omission or alleged
omission from the Registration Statement, any preliminary, final or summary
prospectus contained therein, or any amendment or supplement thereto, to the
extent such untrue statement or omission was made in the Registration Statement
or other document in reliance upon information furnished by the indemnifying
party.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Company pursuant to the foregoing provisions, the Company has been advised that
in the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification of such liabilities
(other than the payment by the Company of expenses incurred by a director,
officer or controlling person of the Company in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered hereby, the Company
will, unless in the opinion of its counsel the matter has been settled by
controlling precedent, submit to a court of appropriate jurisdiction the
question whether such indemnification by it is against public policy as

                PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)
                      OF INFOTEL TECHNOLOGIES (PTE) LTD AND
              NHANCEMENT TECHNOLOGIES INC., AS OF DECEMBER 31, 1997


The following unaudited pro forma combined condensed financial statements assume
a business combination between NHancement Technologies Inc.("NHancement")
including its wholly-owned subsidiaries, Voice Plus, Inc. ("Voice Plus"), which
was acquired in February 1997 immediately prior to the NHancement initial public
offering, Advantis Network & System Sdn Bhd ("Advantis"), which was acquired in
December 1997, and Infotel Technologies (Pte) Ltd ("Infotel"), to be accounted
for as a purchase (the "Acquisition"). The pro forma combined condensed
financial statements are based on the historical financial statements and the
notes thereto of NHancement included in the annual report on Form 10-KSB for the
year ended December 31, 1997, and the historical financial statements of Voice
Plus, Advantis and Infotel for the year ended December 31, 1997.

The pro forma combined condensed balance sheet combines NHancement's audited
December 31, 1997 condensed balance sheet with Infotel's unaudited December 31,
1997 condensed balance sheet, giving effect to the Acquisition and a Preferred
Stock financing as if they had occurred on December 31, 1997. The pro forma
combined condensed statement of operations combines NHancement's historical,
Voice Plus' pro forma and Advantis' pro forma condensed statements of operations
for the year ended December 31, 1997 with the corresponding Infotel condensed
statement of operations for the year ended December 31, 1997, giving effect to
the acquisitions of Infotel, Advantis and Voice Plus, and a Preferred Stock
financing, as if they occurred as of January 1, 1997.

The pro forma information is presented for illustrative purposes only and is not
necessarily indicative of the operating results or financial position that would
have occurred if the acquisitions of Infotel, Advantis and Voice Plus had been
consummated on January 1, 1997, nor is it necessarily indicative of future
operating results or financial position. The unaudited pro forma combined
condensed financial statements do not incorporate any benefits from potential
cost savings or synergies of operations of the combined company.

NHancement estimates that it will incur direct transaction costs of
approximately $49,600 associated with the Acquisition which has been reflected
as a component of the purchase consideration for Infotel. There can be no
assurance that NHancement will not incur additional direct transaction costs
associated with this acquisition in subsequent periods or that management will
be successful in their efforts to integrate the operations of the two companies.

These pro forma combined condensed financial statements should be read in
conjunction with the historical financial statements and the related notes
thereto of NHancement incorporated into this Prospectus by reference to
NHancement's annual report on Form 10-KSB for the fiscal year ended December 31,
1997, and the financial statements and the notes thereto of Infotel included
herein.

                NOTES TO UNAUDITED CONDENSED FINANCIAL STATEMENTS

         BASIS OF PRESENTATION

         The accompanying unaudited condensed financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information. Accordingly, they do not include all of the information
and footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
of normal recurring accruals) considered necessary for a fair presentation have
been included. Operating results for the six-month period ended December 31,
1997 are not necessarily indicative of the results that may be expected for the
year ended June 30, 1998. For further information, refer to the financial
statements and footnotes thereto included in the Company's audited financial
statements for the year ended June 30, 1997.

         The financial statements are stated in Singapore dollars (S$).
Translation of S$ amounts into United States dollars (US$) amounts is included
solely for the convenience of the readers outside Singapore and has been made at
the rate of S$1.67 to US$1.00, the approximate exchange rate at December 31,
1997. No representation is made that the S$ amounts could have been, or could
be, converted into US dollars at that or any other rate.

         SUBSEQUENT EVENTS

         On January 5, 1998, the Company paid an interim dividend of 810.81%,
less 26% tax, amounting to S$3 million for the year ending June 30, 1998.

                         REPORT OF INDEPENDENT AUDITORS


To the Board of Directors and Shareholders
Infotel Technologies (Pte) Ltd


         We have audited the accompanying balance sheets of Infotel Technologies
(Pte) Ltd as of June 30, 1996 and 1997, and the related statements of
operations, shareholders' equity and cash flows for each of the three years in
the period ended June 30, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

         We conducted our audits in accordance with United States generally
accepted auditing standards. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by the management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Infotel Technologies
(Pte) Ltd at June 30, 1996 and 1997, and the results of its operations and its
cash flows for each of the three years in the period ended June 30, 1997, in
conformity with United States generally accepted accounting principles.

1.   ORGANIZATION, BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

   Description of Business

     The Company was incorporated in Singapore on October 21, 1983 as a private
company limited by shares under the name of Green Trading Pte Ltd and changed
its name to Infotel Technologies (Pte) Ltd ("Infotel") on March 27, 1984.
Revenues are earned by supplying equipment, systems, and services in the
telecommunications and information technology markets. The Company also provide
technical services in a range of coordinated multidisciplinary services, from
radio communications to computer networking applications; and from electronic
test and measuring equipment to turn-key projects.

   Basis of presentation

     The Company maintains its records and prepares its statutory financial
statements in accordance with the provisions of Singapore Companies Act, Cap. 50
and Singapore Statements of Accounting Standard. The accompanying financial
statements differ from the financial statements issued for statutory purposes in
Singapore in that they reflect certain adjustments, not recorded in Infotel's
books, which are appropriate to present the financial position, results of
operations and cash flows in accordance with United States generally accepted
accounting principles ("US GAAP"). The principal adjustments relate to: (1)
foreign currency translation; (2) deferred income taxes; (3) accounting for
marketable securities held for trading; and (4) proposed/paid dividends.

   Foreign Currency Translation

     Infotel considers Singapore dollar as its functional currency. Foreign
currency transactions are converted into Singapore dollars at rates of exchange
approximating those ruling at transaction dates. Foreign currency assets and
liabilities are translated into Singapore dollars at the rates ruling at the
balance sheet date. All profits and losses on exchange are dealt with through
the profit and loss account.

       The financial statements are stated in Singapore dollars (S$).
Translation of S$ amounts into United States dollars (US$) amounts is included
solely for the convenience of the readers outside Singapore and has been made at
the rate of S$1.67 to US$1.00, the approximate exchange rate at December 31,
1997. No representation is made that the S$ amounts could have been, or could
be, converted into US dollars at that or any other rate.

   Use of Estimates

     The preparation of financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.

   Inventory

     Inventory consists of parts and equipment for resale and is stated at the
lower of cost or net realizable value which approximates market value. Cost is
determined on a first-in-first-out basis. Net realizable value is arrived at
after due allowance is made for damaged, obsolete and slow-moving inventories.

   Fixed assets and depreciation

     Fixed assets are stated at historical cost. Depreciation is provided on a
straight-line basis over the estimated useful lives of the fixed assets ranging
from 3 to 5 years.

   Revenue recognition

     Sales under fixed price contracts in progress is recognized under the
percentage-of-completion method of accounting in which the estimated sales value
is determined on the basis of physical completion to date (the total contract
amount multiplied by percent of performance to date less sales value recognized
in previous periods). Claims for extra work are included in revenues when
collection is probable.

     Costs comprise material, sub-contracting fee and other directly related
expenses. Provisions for estimated losses on uncompleted contracts are made in
the period in which such losses are determined. Provisions are made to cover
contingency and remedial work that may be necessary.

     The current asset, "Costs and estimated earnings in excess of billings on
uncompleted contracts," represents revenues recognized in excess of amounts
billed. The current liability, "Billings in excess of costs and estimated
earnings on uncompleted contracts," represents amounts billed in excess of
revenues recognized.

     Revenue from the sale of products comprising parts and equipment are
recognized upon passage of titles to the customers which generally coincides
with their delivery and acceptance.

     POLICIES - (CONTINUED)

   Cash and cash equivalents

     For purposes of statement of cash flows, the Company considers highly
liquid investments with a maturity of three months or less when purchased to be
cash equivalents.

   Marketable securities

     Effective July 1, 1995, the Company adopted Statement of Financial
Accounting Standard No. 115, "Accounting for Certain Investments in Debt and
Equity Securities." Under Statement No. 115, debt and marketable securities are
required to be classified in one of the three categories: trading,
available-for-sale, or held to maturity. The Company's debt and equity
securities qualify under the provisions of Statement No. 115 as trading
securities. Such securities are recorded at fair value, and unrealized holding
gains and losses are included in earnings.

     Dividend income is accrued on the basis of the date dividend is declared by
the investee company. Interest income is taken up on an accrual basis.

   Income taxes

     The Company computes and records income tax in accordance with the
liability method of Statement of Financial Accounting Standard No.109
"Accounting for Income Taxes."

     Deferred income taxes are provided for temporary differences between the
financial reporting and tax basis of the Company's assets and liabilities at
enacted tax rates in effect when the temporary differences will reverse.

</TABLE>

     The deferred tax provision for 1996 and 1997 resulted primarily from the
timing differences between financial and income tax reporting for depreciation
of fixed assets and realization of foreign exchange differences.

6.   RELATED PARTY TRANSACTIONS

     During the year ended June 30, 1997, the Company sold a motor vehicle (with
net book value of $0) to a director of the Company, Mr. James Han, for S$65,000
and realized a gain on disposal of fixed asset for the same amount.

7.     SUBSEQUENT EVENTS

     In January 1998, the Company entered into a definitive agreement with
NHancement Technologies Inc. ("NHancement"), a company currently listed on the
Nasdaq SmallCap Market System for the acquisition of the Company by NHancement.
Closing of the transaction is contingent upon NHancement obtaining the financing
necessary to complete the acquisition.

     On January 5, 1998, the Company paid an interim dividend of 810.81%, less
26% tax, amounting to S$3 million for the year ending June 30, 1998.

       reported on the Nasdaq SmallCap Market System, on May 11, 1998.

       issuance of certain shares of Common Stock into which shares of the
       Series A Convertible Preferred Stock are convertible.

Corporation Law of Delaware, including circumstances in which indemnification is
otherwise discretionary. The Company believes that these provisions are

with a $5.0 million coverage limit per occurrence and $5.0 million in the
aggregate per policy year.

Item 17. Undertakings.

         The undersigned Registrant hereby undertakes:

(1)      To file, during any period in which it offers or sell securities, a
         post-effective amendment to this Registration Statement to:

               (i)   Include any prospectus required by Section 10(a)(3) of the
                     Securities Act of 1933;

               (ii)  Reflect in the prospectus any facts or events arising after
                     the effective date of the Registration Statement (or the
                     most recent post-effective amendments thereto) which,
                     individually or in the aggregate, represent a fundamental
                     change in the information set forth in the Registration
                     Statement. Notwithstanding the foregoing, any increase or
                     decrease in volume of securities offered (if the total
                     dollar value of securities offered would not exceed that
                     which was registered) and any deviation from the low or
                     high and of the estimated maximum offering range may be
                     reflected in the form of



                                      II-2
<PAGE>   50

                     prospectus filed with the Commission pursuant to Rule
                     424(b) if, in the aggregate, the changes in volume and
                     price represent no more than a 20% change in the maximum
                     aggregate offering price set forth in the "Calculation of
                     Registration Fee" table in the effective Registration
                     Statement; and

               (iii) Include any material information with respect to the plan
                     of distribution not previously disclosed in the
                     Registration Statement or any material change to such
                     information in the Registration Statement;

         provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if
         the information required to be filed with a post-effective amendment by
         those paragraphs is contained in periodic reports filed with or
         furnished to the Commission by the Registrant pursuant to Section 13 or
         15(d) of the Securities Exchange Act of 1934 that are incorporated by
         reference in the Registration Statement.

(2)      That for determining any liability under the Securities Act of 1933,
         each such post-effective amendment shall be deemed to be a new
         registration of the securities offered, and the offering of the
         securities at that time to be the initial bona fide offering thereof.

(3)      To remove from registration by means of a post-effective amendment any
         of the securities that remain unsold at the termination of the
         offering.

         The undersigned hereby undertakes that, for purposes of determining any
liability under the Securities Act of 1933, each filing of the registrant's
annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act
of 1934 that is incorporated by reference in the registration statement shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

         Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the Registrant pursuant to the foregoing provisions, or otherwise, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.

         In the event that a claim for indemnification against such liabilities
(other than the payment by the Registrant of expenses incurred or paid by a
director, officer or controlling person of the Registrant in the successful
defense of any action, suit or proceeding) is asserted by such director, officer
or controlling person in connection with the securities being registered, the
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act and will be governed by the final adjudication
of such issue.

         under sub-clause (D), then the number of Additional Consideration

        Additional Consideration Shares to be issued by the Purchaser with

        Consideration Shares and the Additional Consideration Shares. The
        aggregate redemption price for all of the Initial Consideration Shares

        the Cash Portion.

        of transactions) of all of the Initial Consideration Shares:-

        (aa)    at any time on or before the First Anniversary, then all of the
                Initial Consideration Shares issued to date shall be deemed to
                have been redeemed and the Purchaser shall have no obligation
                to issue any Additional Consideration Shares to the Vendors

                Second Anniversary; and

        (bb)    at any time after the First Anniversary but before the Second
                Anniversary, then all of the Initial Consideration Shares and
                Additional Consideration Shares issued to date shall be deemed
                to have been redeemed and the Purchaser shall have no
                obligation to issue any Additional Consideration Shares to the
                Vendors under sub-Clause (C)(i) on the Second Anniversary.

(iii)   If the Purchaser elects to redeem only a portion of the Initial
        Consideration Shares, Additional Consideration Shares (if any) then
        issued prior to the redemption date shall be redeemed in the same
        proportion (the "Relevant Proportion") as the portion of the Initial
        Consideration Shares being redeemed bears to all of the Initial
        Consideration Shares. The redemption price payable for the Initial
        Consideration Shares and Additional Consideration Shares being
        redeemed, shall be equal to the Relevant Proportion of the Cash
        Portion.

(iv)    The Purchaser will be entitled to exercise its option to redeem the
        Initial Consideration Shares and the Additional Consideration Shares,
        regardless of whether or not the restrictions on transfer of any of the
        Initial Consideration Shares described in sub-clause (B)(ii) are
        effective, provided however that the Purchaser will not be entitled to
        redeem the Initial Consideration Shares and the Additional

         assigned or otherwise disposed by the Vendors in accordance with the
         provisions of sub-clause (B)(ii).

 (v)     In the event that any Vendor so sells, transfers, assigns or otherwise
         disposes of his Initial Consideration Shares and/or Additional
         Consideration Shares, the aggregate price payable to all Vendors for
         redemption of all Initial Consideration Shares and Additional
         Consideration Shares shall be reduced in the same proportion as the
         proportion which the number of Initial Consideration Shares and/or
         Additional Consideration Shares so sold, transferred, assigned or
         otherwise disposed bears to all Initial Consideration Shares and (as
         then issued) all Additional Consideration Shares respectively.

 (vi)    For the avoidance of doubt, the Initial Consideration Shares and the
         Additional Consideration Shares shall not be redeemable by the
         Purchaser under the provisions of this sub-Clause (D) following the
         Second Anniversary.

         provided however that the Purchaser shall cease to be liable to make

                  Company whether or not such person would commit a breach of
                  contract by reason of transferring business; and

         (v)      at any time after the date of this Agreement, directly or
                  indirectly use or attempt to use in the course of any
                  business on his own account or in conjunction with or on
                  behalf of any person, firm or company, any trade or service
                  mark, trade name, design or logo (whether registered or not)
                  used in the business of the Company or any other name, logo,
                  trade or service mark or design which is or might be

         earlier of:-

         (aa)     the date falling one year after the date on which the
                  Purchaser shall have paid up to $3,200,000.00 in aggregate by

 (D)     Separate Covenants

         Each of the undertakings in sub-clauses (B) and (C) shall be construed

         sub-clauses (B) and (C) are reasonable and necessary for the
         protection of the Purchaser's legitimate interests in the goodwill of
         the Company, but if any such restriction or undertaking shall be found
         to be void or voidable but would be valid and enforceable if some part
         or parts of the restriction or undertaking were deleted, such
         restriction or undertaking shall apply with such modification as may
         be necessary to make it valid and enforceable.

 (F)     Void or Unenforceable Restrictions

         Without prejudice to sub-clause (E), if any restriction or undertaking
         is found by any court or other competent authority to be void or

                                      20.



        replace such void or unenforceable restriction or undertaking with a

        officers or employees shall, make use of or divulge to any third party

        confidential on terms equivalent to this Clause) any confidential
        information relating to the Company save only:-

        reason not completed hereunder, the Purchaser shall not and shall
        procure that none of its officers or employees shall, make use of or

        provided however that the Directors may prior to Completion (without
        the Purchaser's consent) and subject to the requirements of Section 403
        of the Companies Act, declare interim net dividends of an aggregate
        amount not exceeding S$3,000,000.00 in respect of the Company's
        financial year ending on 30th June 1998 and in connection therewith:-

        (1)          such interim net dividends shall be declared on the basis
                     that they shall be payable after the Directors have
                     ascertained the quantum of cash, cash equivalents and
                     marketable securities owned by the Company as at 31st
                     December 1997;

        (2)          if the quantum so determined has an aggregate value equal
                     to or greater than S$1,500,000.00, the Directors shall
                     thereupon be entitled to pay the full amount of the
                     interim dividends so declared;

        (3)          if the quantum so determined has an aggregate value of
                     less than S$1,500,000.00, the Directors shall forthwith
                     revoke the interim net dividends so declared by the amount
                     of the difference between the quantum so determined and
                     S$1,500,000.00, and pay out to the Vendors the amount
                     remaining as interim net dividends;

        (4)          for purposes of calculating the said S$1,500,000.00
                     quantum, the sum of S$450,000.00 paid to Motorola ISG on
                     29th December 1997 in respect of invoice nos. 2786375,

                     added back and deemed not to have been paid out by the
                     Company; and

        (5)          in the event that the profits of the Company distributable
                     as dividends shall, on the basis of the audited accounts
                     in respect of financial year ending on 30th June 1998, be
                     less than the amount of interim net dividends declared and
                     paid under this proviso, the Vendors shall forthwith on
                     demand by the Company repay the difference between the
                     amounts of the distributable profits and the interim net
                     dividends.

(F)     Further Disclosure by Vendors

        The Vendors without prejudice to sub-clause (E) shall forthwith
        disclose in writing to the Purchaser any matter or thing which may
        arise or become known to any Vendor after the date hereof and before
        Completion which is inconsistent with any of the Warranties in any
        material respect or which might make any of them inaccurate or
        misleading in any material respect if they were given at any and all
        times from the date hereof up to Completion or which is material to be
        known to a purchaser for value of the Sale Shares.

(G)     Rescission

        In the event of any act or omission which would make any of the
        Warranties inaccurate or misleading in any material respect becoming

                                      25.



         known to the Purchaser before Completion or in the event of it
         becoming apparent on or before Completion that any Vendor is in breach
         of any of the Warranties in any material respect or any other material
         term of this Agreement, the Purchaser may at its option either:-

         (i)      rescind this Agreement by notice in writing to the Vendors;
                  or

         (ii)     proceed to Completion but without prejudice to its right to
                  claim for breach of this Agreement or such Warranties.

 (H)     Waiver of Claims

         Each Vendor undertakes to the Purchaser that it will not make or
         pursue any claim which it has or may have against the Company or any
         of the Employees (referred to in paragraph 2.11(B)(1) of Schedule 2)
         in respect of or arising out of the Warranties or any information
         supplied by them to or on behalf of the Vendors or any Vendor's
         professional advisers on or prior to the date hereof.

 (I)     Vendor Protection

         The liability of the Vendors in respect of any claim under or in
         connection with the Warranties (each such claim, a "Relevant Claim")
         shall be limited as follows:-

         (i)      the aggregate liability of the Vendors in respect of Relevant
                  Claims shall be limited to S$11,000,000.00;

         (ii)     the Vendors shall not be liable in respect of a Relevant
                  Claim unless the aggregate liability of the Vendors in
                  respect of all Relevant Claims exceeds S$100,000.00 in which
                  case the Vendors shall jointly and severally be liable for
                  the whole amount and not merely the excess over S$100,000.00;

         (iii)    the Vendors shall have no liability in respect of any
                  Relevant Claim unless the Purchaser shall have given notice
                  in writing to the Vendors of such claim on or before 31st
                  December 1999;

         (iv)     if the Vendors pay to or for the benefit of the Purchaser an
                  amount in respect of any Relevant Claim and any of the
                  Purchaser or the Company subsequently receives from any other
                  person any payment in respect of the matter giving rise to
                  the Relevant Claim, the Purchaser shall thereupon pay to the
                  Vendors (unless otherwise requested, in the Shareholding
                  Proportion) an amount equal to the payment received, after
                  having taken into account any cost, liability (including tax
                  liability) or expense in respect thereof and except to any
                  extent that the liability of the Vendors in respect of the





<PAGE>   26
INFOTEL - Share Sale Agmt

                                      26.



                Relevant Claim was reduced to take account of such payment;

        (v)     in respect of any claim made by or against the Company in
                relation to third parties which is subject- matter of a
                Relevant Claim, the Purchaser shall at its absolute discretion,
                acting reasonably and in good faith, take all reasonable steps
                to defend or pursue such claim;

5       DETERMINATION OF NUMBER OF INITIAL CONSIDERATION SHARES

        The number of Initial Consideration Shares (denoted "N" below) to be
        issued by the Purchaser to the Vendors as at Completion, shall be
        calculated in accordance with the following formula (rounded downwards
        to the nearest whole number):-


                N = ( P - R )
                    ---------
                        X
        where:-

        "P"     means the US Dollar Equivalent of S$3,750,000.00;

        "R"     means the US Dollar Equivalent of the amount (if any) by which
                the Net Tangible Assets of the Company as at 31st December 1997
                as shown by the Completion Accounts, are less than S$4,800,000
                by an amount in excess of S$200,000; and

        "X"     means US$5.00 (unless the Purchaser's stock of which the
                Initial Consideration Shares form part, are split or a rights
                offering is made in respect thereof, in which case "X" shall be
                adjusted accordingly),

        Provided however that:-

        (a)     If, as calculated in accordance with this paragraph 5, "N"
                (rounded downwards to the nearest whole number) shall either be
                zero or a negative number, the number of Initial Consideration
                Shares to be issued shall be zero.

        (b)     If, during the period from the date of this Agreement up to the
                date of Completion, any dividends shall have been declared in
                relation to shares in the common stock of the Purchaser, the
                number of Initial Consideration Shares shall be increased by
                the amount (denoted "I") calculated in accordance with the
                following formula (rounded downwards to the nearest whole
                number):-

                         I =   V   
                            -------
                               X

                where:-

                "V"      is the value (in US Dollars) of dividends notionally
                         payable in respect of the number of Initial
                         Consideration Shares denoted "N" calculated in
                         accordance with this paragraph 5 (rounded downwards to
                         the nearest whole number); and

                "X"      is as defined above.

        (c)     If, during the period from the date of this Agreement up to the
                date of Completion, the aggregate percentage interest of the
                Vendors in the capital of the Purchaser shall be diluted by
                reason only that any rights offering or bonus issue is made by

                  the Purchaser, the number of Initial Consideration Shares
                  shall be adjusted accordingly such that such aggregate
                  percentage interest of the Vendors is maintained. Such
                  aggregate percentage interest shall be ascertained on the
                  basis of the proportion which the number of Initial
                  Consideration Shares denoted "N" calculated in accordance
                  with this paragraph 5 (rounded downwards to the nearest whole
                  number), bears to all shares in the common stock of the
                  Purchaser which are issued as at the date of this Agreement.
                  For the avoidance of doubt, there shall be no adjustment of
                  the number of Initial Consideration Shares under this
                  sub-paragraph (c) in the event that the Purchaser allots
                  fresh shares in its common stock otherwise than by reason of
                  a rights offering or bonus issue.

 6       INTERACTION WITH OTHER PROVISIONS

         If the Purchaser shall have any claim against the Vendors under this
         Agreement in respect of any liability or deficiency which is taken
         into account in the Completion Accounts the amount of such liability
         or deficiency so taken into account shall be deducted from the amount
         of the Purchaser's claim but, save as aforesaid, preparation and
         acceptance of the Completion Accounts by the Purchaser shall be
         without prejudice to any claim which the Purchaser may have against
         any Vendor under or in respect of any breach of this Agreement.

                          (referred to in clause 3.4)



 1.        The Employee shall be entitled to receive incentive bonuses as
           declared by the Board if the Company earns Profit After Tax (as
           defined below) in respect of any of the financial years ending 30th
           June 1998, 30th June 1999 and 30th June 2000 respectively (each, a
           "Relevant Financial Year") on condition that the Employee:-

           (a)        has been in the employ of the Company for not less than
                      six months;

           (b)        is in the employ of the Company on the last day of the
                      Relevant Financial Year in question; and

           (c)        is in the employ of the Company at the time when payment
                      of the incentive bonus is due to be made under this
                      Schedule 2,
            
           Provided However that the Company shall no longer be required to pay
           to the Employee the incentive bonus under this Schedule 2, once the
           Company has paid an aggregate of S$300,000 by way of incentive
           bonuses to the Specified Employees, being the Employee and such
           other key employees of the Company as the Board shall specify. The
           calculation of this aggregate amount of S$300,000 paid by the
           Company shall take into account any and all contributions which the
           Company (as employer) is required to make to the Central Provident
           Fund in connection with the incentive bonuses.


 1.        The term "Profit After Tax" as used in this Schedule 2 means the
           profit after tax earned by the Company in respect of any such
           financial year, as shall be conclusively determined by accountants
           appointed by the Company's shareholders for this purpose. Such
           determination shall:-

           (a)        be made on the basis of the Company's audited accounts in
                      respect of the Relevant Financial Year (which accounts
                      shall be prepared by the Company's auditors for the time
                      being in accordance with generally accepted accounting
                      principles); and

           (b)        exclude all amounts by way of incentive bonuses payable
                      in respect of the Relevant Financial Year in question.


 2.        The Employee shall in respect of each Relevant Financial Year
           receive 1.5% of the Profit After Tax for that Relevant Financial
           Year as incentive bonus, provided





<PAGE>   96



          that if the Employee shall have been in the employ of the Company for
          less than one year at the end of a Relevant Financial Year, the
          amount of incentive bonus paid to him shall be pro-rated according to
          the number of months he has been employed by the Company in that
          Relevant Financial Year.

4.        Any such payment due to the Employee as aforesaid shall be made to
          the Employee within sixty (60) days of finalisation of the Company's
          audited accounts for each Relevant Financial Year.

5.        In the event that less than S$300,000.00 in aggregate shall have been
          declared by the Company as at the end of the Relevant Financial Year
          ending 30th June 2000, on condition that the Employee:-

          (a)        has been in the employ of the Company for not less than
                     six months;

          (b)        is in the employ of the Company on the last day of the
                     Relevant Financial Year in question; and

          (c)        is in the employ of the Company at the time when payment
                     of the relevant amount is due to be made under this
                     paragraph 5,

the Company shall, irrespective of whether the Company shall have earned any
Profit After Tax for the Company's financial year ending 30th June 2001, pay to
the Employee his proportionate share (which shall be in the proportion of his
percentage share of the aggregate incentive bonus for a Relevant Financial
Year) of the amount of the shortfall below S$300,000.00, within sixty (60) days
of finalisation of the Company's audited accounts for that financial year. In
calculating the amount to be paid to the said Specified Employee, any and all
contributions which the Company (as employer) is required to make to the
Central Provident Fund in connection with such payment shall be taken into
account.

         Re:      Registration Statement on Form S-3

 Ladies and Gentlemen:

         We furnish this opinion as counsel for NHancement Technologies Inc., a
 Delaware corporation ("NHancement"), in connection with the Registration
 Statement on Form S-3 (the "REGISTRATION STATEMENT") filed by NHancement with
 the Securities and Exchange Commission on May 14, 1998, providing for the
 registration under the Securities Act of 1933, as amended, of (i) a sufficient
 number of shares of Common Stock, par value $0.01 per share, of NHancement (the
 "Shares") issuable to The Endeavour Capital Fund S.A. and AMRO INTERNATIONAL
 S.A. (the "Initial Investors") upon conversion of the shares of Series A
 Convertible Preferred Stock held by the Initial Investors pursuant to the terms
 of that certain Securities Purchase Agreement dated April 13, 1998 by and
 between NHancement and the Initial Investors (the "Purchase Agreement"), and
 (ii) One Hundred Fifty Thousand (150,000) shares of Common Stock, par value
 $0.01 per share, of NHancement issued to James S. Gillespie (the "Issued
 Shares").

         In our capacity as counsel to NHancement, we have examined, among
 other things, originals, or copies identified to our satisfaction as being
 true copies of such documents as we have deemed necessary, including
 resolutions by the stockholders and the board of directors authorizing the
 issuance of the Shares to the Initial Investors upon conversion of their
 shares of Series A Preferred Stock and filing of the Registration Statement,
 and we have obtained from officers and representatives of NHancement such
 other certificates and assurances as we consider necessary for the purposes of
 this opinion.

         In those cases in which we have not been involved directly in the
 preparation, execution or the filing of a document, we have assumed that (i)
 the document reviewed by us is an original document, or a true and accurate
 copy of the original document, and has not been subsequently amended, (ii) the
 signatures on each original document are genuine, and (iii) each party who
 executed the document had proper authority and capacity to execute such
 document.

         On the basis of our examination, and in reliance thereon and on our
 consideration of such other matters of fact and questions of law as we
 consider relevant in the circumstances, we are of the opinion that, (i) when
 issued and paid for in accordance with the terms of, and after satisfaction of
 the conditions stated in the Purchase Agreement, the Shares will be legally
 issued, fully paid and nonassessable and (ii) the Issued Shares are legally
 issued, fully paid and nonassessable.

         We hereby consent to the use of our name under the caption "Legal
 Matters" in the prospectus which constitutes a part of the above-mentioned
 Registration Statement, and to the filing of this opinion as an exhibit to
 said Registration Statement.


                                           Very truly yours,


                                           Tomlinson Zisko Morosoli & Maser LLP
