(1)     The 11,047,500 shares of Common Stock being registered hereunder include
        (i) 11,000,000 shares of Common Stock which represents the registrant's
        good faith estimate of the maximum number of shares of Common Stock
        issuable upon conversion of the 1,500 shares of Series F Convertible
        Preferred Stock issued in a private placement transaction on October 21,
        1998 and the 1,500 shares of Series F Convertible Preferred Stock
        issuable in a private placement transaction upon effectiveness of this
        registration statement and the satisfaction of certain other closing
        conditions, (ii) 25,000 shares of Common Stock issuable upon the
        exercise of certain warrants held by Reedland Capital Partners and World
        Capital Funding LLC (together, the "Consultants"), and (iii) 22,500
        shares of Common Stock currently held by the Consultants. As of January
        7, 1999, the number of shares issuable upon conversion of the Series F
        Convertible Preferred Stock is 5,073,927, assuming completion of both
        tranches of Series F Preferred Stock as of such date. In accordance with
        Rule 416 under the Securities Act of 1933, as amended (the "Act"), this
        registration statement also covers such indeterminate number of shares
        of Common Stock that may be offered or issued pursuant to terms which
        provide for a change in the amount of shares of Common Stock being
        offered or issued to prevent dilution resulting from stock splits, stock
        dividends or similar transactions.
    
   

(2)     These figures are estimates made solely for the purpose of calculating
        the registration fee in accordance with Rule 457 under the Securities
        Act of 1933, as amended. This amendment increases the number of shares
        of Common Stock to be registered by 1,544,177 from those referred to in
        the original filing at which time the registrant paid a registration fee
        of $2,990 (based on a per share price of $1.09375). Based upon the
        average of the high and low prices per share of Common Stock reported on
        the NASDAQ National Market system on January 7, 1999, the additional fee
        paid herewith for adding such 1,544,177 shares is $310.
    

THE REGISTRANT HEREBY AMENDS THIS REGISTRATION STATEMENT ON SUCH DATE OR DATES
AS MAY BE NECESSARY TO DELAY ITS EFFECTIVE DATE UNTIL THE REGISTRANT SHALL FILE
A FURTHER AMENDMENT WHICH SPECIFICALLY STATES THAT THIS REGISTRATION STATEMENT
SHALL THEREAFTER BECOME EFFECTIVE IN ACCORDANCE WITH SECTION 8(a) OF THE

                                  RISK FACTORS

   
        An investment in Alpha-Beta common stock involves various risks. This
prospectus contains forward-looking statements within the meaning of the federal
securities laws. You are cautioned that any such forward-looking statements are
not guarantees of future performance and involve risks and uncertainties. Actual
events or results may differ materially from those discussed in the
forward-looking statements as a result of various factors, including the factors
referenced in Alpha-Beta's documents which are filed with the SEC and which are
incorporated by reference herein. In deciding whether or not to invest in
Alpha-Beta common stock, you should consider the following risk factors:
    

   
ALPHA-BETA IS UNCERTAIN OF ITS ABILITY TO OBTAIN FINANCING NECESSARY TO 
CONTINUE ITS OPERATIONS
    

   
        Alpha-Beta cannot assure you that it will be able to obtain financing
necessary to continue its operations. Based upon its current rate of
expenditures, Alpha-Beta expects that its current funds and the funds to be
received from the sale of the second tranche of Alpha-Beta preferred stock are
sufficient to meet its operating expenses and capital requirements through
January 1999. Alpha-Beta currently does not have any committed source of capital
to fund its business after January 1999.
    

   
        Alpha-Beta needs to raise substantial additional capital to fund its
operations, including the completion of the Phase III clinical trial of its lead
product, Betafectin(R). Alpha-Beta anticipates that it needs to raise at least
$10 million to continue its operations through the end of 1999. Alpha-Beta is
seeking such additional funding through public or private equity or debt
financings, licensing, marketing and distribution arrangements with
pharmaceutical or biotechnology companies and from other sources.
    

   
        In the short-term, Alpha-Beta's ability to raise additional funds may
well be determined by the results of the interim analysis to be released in
early 1999 in connection with the Phase III clinical trial of Betafectin(R).
Additionally, in the long-term, Alpha-Beta's ability to raise additional funds
or to enter into collaborative or other arrangements may depend upon a number of
factors including the following:
    

   
     *      the final results of Alpha-Beta's clinical development programs;
    

   
     *      discussions with the FDA; and
    

   
     *      the overall market for biotechnology stocks.
    

   
        Alpha-Beta may not be able to obtain additional financing on acceptable
terms, if at all. If adequate funds are not available, Alpha-Beta's business
will be materially adversely affected as Alpha-Beta will have to reduce or
eliminate certain areas of research, product development, manufacturing and
marketing activity, or otherwise severely modify its business strategy.
Ultimately, if Alpha-Beta does not obtain additional financing on acceptable
terms, it may need to modify its business strategy of remaining independent. At
such time, Alpha-Beta will consider various strategic alternatives such as the
sale of rights to certain technologies, candidate drugs, potential markets and
other assets, as well as the possibility of merging with another company.
    

   
ALPHA-BETA IS UNCERTAIN OF ITS FUTURE PROFITABILITY
    

   
        Alpha-Beta cannot assure you that it will be able to achieve
profitability at all or on a sustained basis. Alpha-Beta has been operating at a
loss since its inception in March 1988. As of September 30, 1998, Alpha-Beta had
accumulated net losses of approximately $157 million. Alpha-Beta will continue
to incur significant costs in connection with the establishment and development
of its research and development programs and its manufacturing, sales,
marketing, quality control, regulatory and administrative capabilities. As a
result, Alpha-Beta expects to continue to incur substantial operating losses for
the next several years. Alpha-Beta cannot predict the size of such losses. To
achieve profitability Alpha-Beta must successfully complete development of its
products, obtain regulatory approvals, develop its manufacturing capabilities
and establish sales and marketing capabilities.

ALPHA-BETA MAY BE UNABLE TO OBTAIN REGULATORY APPROVAL FOR ITS PRODUCTS, 
INCLUDING ITS LEAD PRODUCT, BETAFECTIN(R)
    

   
        Alpha-Beta cannot assure you that it will obtain regulatory approval for
its products, including its lead product Betafectin(R), within a reasonable
period of time, if at all. None of Alpha-Beta's products are expected to be
commercially available prior to late-1999 at the earliest.
    

   
        Numerous governmental authorities in the United States and other
countries including the FDA regulate Alpha-Beta's research, development and
clinical programs and manufacturing operations. All of Alpha-Beta's products
require governmental approvals for commercialization which have not yet been
obtained. The regulatory process includes rigorous preclinical, clinical and
post-clinical testing of Alpha-Beta's products to establish their safety and
effectiveness. As a result, the approval process requires many years to complete
and the expenditure of substantial resources. Problems such as toxicity or
adverse event reporting during clinical trials may require Alpha-Beta to
terminate the trials at any time.
    

        Data obtained from preclinical and clinical activities are susceptible
to varying interpretations which could delay, limit or prevent regulatory
approval. In addition, changes in regulatory policies for drug approval during
Alpha-Beta's product development and regulatory review may result in delays or
rejection.

   
        Alpha-Beta's lead product, Betafectin(R), is currently in Phase III
clinical trial for the prevention of serious post-operative infections in upper
gastrointestinal surgery patients. The study is expected to be completed by the
end of 1999 and will include an interim analysis in early 1999. If the clinical
trial for Betafectin(R) is successful, Alpha-Beta will file with the FDA for
approval to market Betafectin(R). If it is not successful, Alpha-Beta will
reduce or eliminate certain areas of research, product development,
manufacturing and marketing activity, and it may need to modify its business
strategy of remaining independent and consider various strategic alternatives
such as the sale of rights to certain technologies, candidate drugs, potential
markets and other assets, as well as the possibility of merging with another
company.
    

   
        Even if regulatory approval is obtained, Alpha-Beta will still be
subject to continual regulatory review and periodic inspections. If a regulatory
authority discovers previously unknown problems, it may impose further
restrictions, including requiring the removal of a product from the market.
    

        If Alpha-Beta fails to comply with applicable regulatory requirements,
it may be subject to fines, suspensions of regulatory approvals, product
recalls, operating restrictions and criminal prosecution.

   
ALPHA-BETA MAY BE UNABLE TO SUCCESSFULLY MARKET AND SELL ITS PRODUCTS
    


   
        Alpha-Beta cannot assure you that it will be able to successfully market
and sell its products if and when regulatory approval is obtained. To be
successful, Alpha-Beta will have to manufacture its products in commercial
quantities, within regulatory requirements and at competitive costs. Alpha-Beta
currently has no experience in marketing, sales or distribution of commercial
products. To market any of its products, Alpha-Beta will need to develop a
substantial marketing and sales force with technical expertise and the
capability to support distribution. Alpha-Beta may not be able to establish the
necessary sales and distribution capabilities or successfully gain market
acceptance for its products. Alpha-Beta is currently seeking a strategic partner
with the necessary sales and distribution capabilities and expertise to assist
in the commercialization of Betafectin(R). Alpha-Beta may not be able to enter
into such a strategic relationship without undue delays or expenditures.
    

   
       In June 1994, Alpha-Beta completed construction of a commercial-scale
manufacturing facility in Smithfield, Rhode Island. This facility is presently
being operated to manufacture clinical quantities of Betafectin(R). While
Alpha-Beta believes this facility will have the capacity to manufacture
sufficient quantities of Betafectin(R) for clinical trials and the commercial
introduction of the product, Alpha-Beta cannot assure you that the Betafectin(R)
plant will have sufficient capacity to satisfy Alpha-Beta's product requirements
or that Alpha-Beta will be able to manufacture Betafectin(R) at acceptable
costs.
    

                                       3

<PAGE>   6


   
ALPHA-BETA FACES INTENSE INDUSTRY COMPETITION
    

   
        Alpha-Beta cannot assure you that its business will not fail as a result
of the intense competition it faces from pharmaceutical and biotechnology
companies, universities and other research institutions. To be successful,
Alpha-Beta must develop and maintain a competitive position in the development
of products and technologies in its area of focus. Alpha-Beta's competitors may
succeed in developing technologies and products that are more effective than any
which have been or are being developed by Alpha-Beta or that render Alpha-Beta's
technologies or products obsolete or noncompetitive. Moreover, Alpha-Beta's
competitors may obtain regulatory approval for the commercialization of their
products more rapidly or effectively than Alpha-Beta. Finally, many of
Alpha-Beta's competitors have substantially greater research and development
capabilities, clinical, manufacturing, regulatory and marketing experience and
financial and managerial resources than Alpha-Beta has.
    

   
ALPHA-BETA MAY NOT BE ABLE TO HIRE AND RETAIN KEY PERSONNEL
    

   
        Alpha-Beta cannot assure you that it will be successful in hiring or
retaining the personnel it requires for growth and development. Alpha-Beta is
highly dependent on the members of its management and scientific staff, the loss
of some of whom could have a material adverse effect on Alpha-Beta. Alpha-Beta
also depends on its collaborators, each of which have commitments that may limit
their availability to Alpha-Beta. In addition, Alpha-Beta believes that its
future success will depend in large part upon its ability to attract and retain
highly skilled scientific, managerial and marketing personnel, particularly as
Alpha-Beta expands its activities in clinical trials, the regulatory approval
process, sales and manufacturing. Alpha-Beta faces significant competition for
such personnel from other companies, research and academic institutions,
government entities and other organizations. The failure to hire and retain key
personnel could materially and adversely affect Alpha-Beta's prospects.
    

   
ALPHA-BETA MAY BE UNABLE TO MAKE PAYMENTS ON ITS LOAN FROM RIPA
    

   
        Alpha-Beta cannot assure you that it will be able to continue to make
payments on its loan from the Rhode Island Port Authority and Economic
Development Corporation. In February 1993, Alpha-Beta completed a $30 million
debt financing through RIPA to finance, in large part, the costs of Alpha-Beta's
Betafectin(R) plant. Because this facility was constructed prior to the issuance
of final FDA approval for the commercial sale of Betafectin(R), Alpha-Beta is
obligated to repay the RIPA loan regardless of whether Betafectin(R) is approved
for commercial sales. Alpha-Beta is required to make payments of approximately
$300,000 per month to RIPA over the 20 year term of the RIPA loan. Alpha-Beta's
obligation to repay the loan is subject to acceleration if Alpha-Beta fails to
make any monthly debt service payments, or if certain other events of default
occur. Alpha-Beta may also be required to repay the loan on an accelerated basis
over five years if the enabling legislation under which RIPA issued the bonds
used to fund the loan to Alpha-Beta is eliminated or if the state of Rhode
Island or RIPA is subject to any bankruptcy proceeding. The terms of the RIPA
loan are subject to adjustment in connection with a possible refinancing of the
RIPA bonds by RIPA on December 1, 1999. The financial obligations incurred by
Alpha-Beta in connection with the RIPA debt refinancing could have a material
impact on the ability of Alpha-Beta to conduct its operations.
    

   
ALPHA-BETA DEPENDS ON PATENTS AND PROPRIETARY RIGHTS THAT MAY FAIL TO PROTECT 
ITS BUSINESS
    

   
        Alpha-Beta's success depends, in large part, upon its ability to obtain
patent protection for its products and manufacturing processes, preserve its
trade secrets and operate without infringing the proprietary rights of third
parties.
    

   
        In addition to Alpha-Beta's own patents and patent applications, the
Massachusetts Institute of Technology and The Brigham and Women's Hospital have
exclusively licensed rights in certain patents and patent applications to
Alpha-Beta. Alpha-Beta's future performance is partly dependent upon its ability
to attain certain targets and make specified royalty payments required by the
governing license agreements. Alpha-Beta cannot assure you that it will satisfy
any of these requirements.
    

        Alpha-Beta anticipates seeking additional patents in the future as it
continues to conduct research. However, the patent position of biotechnology and
pharmaceutical firms is often highly uncertain and usually 

                                       4
<PAGE>   7

involves complex legal and factual questions. In addition, the United States
Patent and Trademark Office is substantially backlogged with biotechnology
patent applications, and no consistent policy has emerged regarding the breadth
of claims covered in biotechnology patents. Accordingly, Alpha-Beta cannot
assure you that patent applications relating to its products or technology will
result in patents being issued or that, if issued, such patents will afford
adequate protection to Alpha-Beta or not be challenged, invalidated or
infringed. Furthermore, Alpha-Beta cannot assure you that others will not
independently develop similar products and processes, duplicate any of
Alpha-Beta's products or design around any of Alpha-Beta's patents.

   
        Alpha-Beta may incur substantial costs in defending itself in suits
brought against it or in suits in which Alpha-Beta may assert its patents
against others. If the outcome of any such litigation is adverse to Alpha-Beta,
Alpha-Beta's business could be adversely affected. To determine the priority of
inventions, Alpha-Beta may also have to participate in interference proceedings
declared by the United States Patent and Trademark Office. Such proceedings
could result in substantial costs to Alpha-Beta.
    

        In addition, Alpha-Beta may be required to obtain licenses to patents or
other proprietary rights of third parties. Alpha-Beta cannot assure you that any
licenses required under any such patents or proprietary rights would be made
available on acceptable terms, if at all. If Alpha-Beta does not obtain such
licenses, it could encounter delays in product market introductions while it
attempts to design around such patents or other rights, or be unable to develop,
manufacture or sell products.

        In addition to its patents and patent applications, Alpha-Beta also has
proprietary technology which is not patented or patentable. Alpha-Beta may seek
to protect such technology in part with confidentiality agreements and, if
applicable, inventors' rights agreements with its collaborators, advisors,
employees and consultants. Alpha-Beta cannot assure you that these agreements
will not be breached, that Alpha-Beta will have adequate remedies for any
breach, or that Alpha-Beta's trade secrets will not otherwise be disclosed to,
or discovered by, competitors. Moreover, Alpha-Beta conducts a significant
amount of research through academic advisors and collaborators who are
prohibited from entering into confidentiality or inventors' rights agreements by
their academic institutions.

   
ALPHA-BETA MAY BE SUBJECT TO PRODUCT LIABILITY CLAIMS ARISING OUT OF THE
MANUFACTURE, TESTING AND SALE OF ITS PRODUCTS AND MAY NOT BE ABLE TO OBTAIN OR
MAINTAIN ADEQUATE INSURANCE TO COVER SUCH CLAIMS
    


   
        Alpha-Beta cannot assure you that substantial product liability claims
will not be asserted against it arising out of the manufacture, testing and sale
of its products. The testing, marketing and sale of human therapeutic products
involve an inherent risk of allegations of product liability. While Alpha-Beta
has clinical trials liability insurance, it does not have product liability
insurance coverage for the commercial sale of Betafectin(R). Alpha-Beta cannot
assure you that it will be able to maintain clinical trials liability insurance
on acceptable terms or that such insurance will provide adequate coverage
against potential liabilities. Alpha-Beta will seek to obtain product liability
insurance if and when its products are commercialized. However, Alpha-Beta
cannot assure you that adequate insurance coverage will be available at
acceptable costs, if at all, or that a product liability claim would not
materially adversely affect the business or financial condition of Alpha-Beta.
    

   
UNCERTAIN PHARMACEUTICAL PRICING ENVIRONMENT MAY IMPACT ALPHA-BETA'S BUSINESS
    

   
        Alpha-Beta's ability to commercialize any of its products depends on the
extent to which reimbursements to patients for the cost of such products will be
available from government health administration authorities, private health
insurers and other organizations. Third-party payors are increasingly
challenging the price and cost-effectiveness of medical products and services.
In addition, significant uncertainty exists as to the reimbursement status of
newly approved health care products. Alpha-Beta cannot assure you that its
proposed products will be considered cost effective or that adequate third-party
reimbursement will be available to enable Alpha-Beta to maintain price levels
sufficient to realize an appropriate return on its investment in product
development. Legislation and regulations affecting the pricing of
pharmaceuticals may change before any of Alpha-Beta's proposed products are
approved for commercialization. Adoption of such legislation could further limit
reimbursement for medical products and services.

THE MARKET PRICE OF ALPHA-BETA COMMON STOCK HAS STEADILY DECREASED IN RECENT 
YEARS
    

   
        The market price for Alpha-Beta common stock has steadily decreased in
recent years as a result, at least in part, of the results of its previous
clinical trials. Alpha-Beta cannot assure you that the market price of
Alpha-Beta common stock will not continue to decrease in the future. The
following factors may have a significant effect on the market price of
Alpha-Beta common stock:
    

   
     *      disclosure of interim and final results of clinical testing or 
            regulatory proceedings;
    

   
     *      announcements of technological innovations or new commercial 
            products by Alpha-Beta or its competitors;
    

   
     *      governmental regulation and approvals;
    

   
     *      developments in patent or other proprietary rights;
    

   
     *      public concern as to the safety of products developed by Alpha-Beta;
            and
    

   
     *      future sales of Alpha-Beta common stock in the public market by 
            existing stockholders.
    

   
ALPHA-BETA COMMON STOCK MAY BE DELISTED FROM THE NASDAQ NATIONAL MARKET
    

   
        Alpha-Beta cannot assure that it will be able to satisfy the
requirements of the Nasdaq Stock Market for continued listing of its common
stock on the Nasdaq National Market. The rules of the Nasdaq Stock Market
require that companies listed on the Nasdaq National Market satisfy certain
requirements for listing. Alpha-Beta currently does not satisfy Nasdaq=s $1
minimum bid price requirement and its $4 million minimum net tangible asset
requirement.
    

   
        Alpha-Beta has received a letter from Nasdaq regarding the continued
listing of Alpha-Beta common stock on the Nasdaq National Market and has filed a
plan to achieve compliance with Nasdaq.
    

   
        If Nasdaq delists the common stock from the National Market, the ability
of stockholders of Alpha-Beta to buy and sell shares of Alpha-Beta common stock
may be materially impaired. In addition, the continued delisting of Alpha-Beta
common stock could adversely affect Alpha-Beta's ability to enter into future
equity financing transactions.
    

   
ALPHA-BETA MAY BE REQUIRED TO REDEEM THE ALPHA-BETA PREFERRED STOCK AT A PREMIUM
IF ALPHA-BETA COMMON STOCK IS DELISTED FROM THE NASDAQ NATIONAL MARKET.
    

   
        If the common stock is delisted from the Nasdaq National Market, the
holders of the Alpha-Beta preferred stock are entitled to have each of their
outstanding shares of preferred stock bought back by Alpha-Beta for an amount
equal to 1.30 multiplied by the purchase price per share of preferred stock
($1,000) plus interest at the rate of 6% per annum. In addition, instead of
requiring a buy-back, the holders of the preferred stock may elect to have the
conversion rate for the preferred stock adjusted which would result in the
preferred stock being convertible into more shares of Alpha-Beta common stock.
At this time, Alpha-Beta does not have adequate cash resources available to pay
the applicable repurchase price if the holders of the preferred stock elect a
repurchase and does not have a plan in place to fund such repurchase. If the
holders of the preferred stock elect to adjust the conversion rate upon
delisting, increased dilution to Alpha-Beta's existing stockholders would result
upon conversion of the Alpha-Beta preferred stock.
    

   
HFTP INVESTMENTS MAY NOT BE OBLIGATED TO PURCHASE THE SECOND TRANCHE OF
ALPHA-BETA PREFERRED STOCK IF ALPHA-BETA COMMON STOCK IS DELISTED FROM THE
NASDAQ NATIONAL MARKET.
    

   

        The obligation of HFTP Investments to purchase the second tranche of
preferred stock is contingent upon Alpha-Beta's common stock not having been
suspended by the Nasdaq National Market or the SEC prior to the closing of the
second tranche of preferred stock and Alpha-Beta having not been notified of any
pending
    

                                       6

<PAGE>   9

   
or threatened proceeding or other action to delist or suspend the common stock 
prior to such time. Alpha-Beta believes that (i) the correspondence received 
from Nasdaq regarding the continued listing status of the common stock does not 
constitute a threatened proceeding or action to delist or suspend the common 
stock, and (ii) absent any further action on the part of Nasdaq, HFTP 
Investments is still obligated to purchase the second tranche of preferred 
stock. However, if HFTP Investments does not purchase the second tranche of 
preferred stock, Alpha-Beta will need to immediately locate other financing.
    


   
HOLDERS OF ALPHA-BETA COMMON STOCK WILL EXPERIENCE SUBSTANTIAL DILUTION UPON
CONVERSION OF THE ALPHA-BETA PREFERRED STOCK
    

   
        Holders of Alpha-Beta common stock will experience substantial dilution
upon conversion of the Alpha-Beta preferred stock. As of January 7, 1999,
5,073,927 shares of Alpha-Beta common stock were issuable upon conversion of the
Alpha-Beta preferred stock, assuming completion of the second tranche of
preferred stock as of such date. If HFTP Investments converted all of its shares
of preferred stock as of such date, the total number of shares of Alpha-Beta
common stock outstanding would increase by 24.6%. If the 11,000,000 shares of
Alpha-Beta common stock being registered on behalf of HFTP Investments are
issued upon conversion of the preferred stock, the total number of shares of
common stock outstanding as of January 7, 1999 would increase by 53.3%. The
existence of the preferred stock may adversely affect the terms under which
Alpha-Beta could obtain additional equity capital. The conversion of this
preferred stock may materially adversely affect the market price of the common
stock.
    

   
ALPHA-BETA MAY BECOME SUBJECT TO RULES RELATING TO LOW-PRICED OR PENNY STOCK
    

   
        If, for any reason, Alpha-Beta's common stock does not remain accepted
for listing on the Nasdaq National Market, Alpha-Beta expects that its common
stock would be traded in the over-the-counter markets through the "pink sheets"
or on the NASD's OTC Bulletin Board. In addition, in the event the Alpha-Beta
common stock is delisted from the Nasdaq National Market, the common stock would
be covered by a SEC rule that imposes additional sales practice requirements on
broker-dealers who sell such securities to persons other than established
customers and accredited investors (generally institutions with assets in excess
of $5,000,000 or individuals with net worth in excess of $1,000,000 or annual
income exceeding $200,000 or $300,000 jointly with their spouse). For
transactions covered by the rule, the broker-dealer must make a special
suitability determination for the purchaser and receive the purchaser=s written
agreement to the transaction prior to the sale. Consequently, the rule may
affect the ability of broker-dealers to sell Alpha-Beta common stock and also
may affect the ability of holders of Alpha-Beta common stock to resell their
shares of common stock.
    

   
ANTI-TAKEOVER PROVISIONS COULD IMPACT MARKET PRICE OF ALPHA-BETA COMMON STOCK
    

   
        Alpha-Beta has adopted certain anti-takeover measures discussed below
which are designed to prevent or discourage a hostile acquiror from gaining
control of the company. These provisions may have the effect of delaying,
deterring or preventing a change of control of the company, may discourage bids
for Alpha-Beta common stock at a premium over market prices and may adversely
affect the market price and rights of the holders of common stock.
    

   
     *      Alpha-Beta's Board of Directors has the authority, without further
            action by the holders of Alpha-Beta common stock, to issue
            additional shares of preferred stock and to set the rights of such
            preferred stock. As a result, the Board of Directors may issue
            shares of preferred stock with favorable terms to a
            management-friendly investor in order to discourage a potential
            acquiror from gaining control of the company.
    

   
     *      Alpha-Beta has a adopted a shareholder rights plan which operates to
            cause substantial dilution to a potential acquiror upon the
            consummation of certain transactions if such acquiror does not first
            negotiate with the Board of Directors.
    

   
     *      Alpha-Beta has adopted certain by-law provisions which restrict the
            ability of a potential acquiror, and other stockholders, to remove
            directors or call a special meeting of stockholders.
    


                                       7
<PAGE>   10


   
        In addition, Alpha-Beta is subject to Chapter 110F of the Massachusetts
Corporation Law which prohibits Alpha-Beta from engaging in certain transactions
with stockholders owning in excess of 5% of the outstanding Alpha-Beta common
stock (an "Interested Stockholder") for a period of three years following the
date the stockholder became an Interested Stockholder, unless the transaction is
approved in a prescribed manner.
    

   
THE YEAR 2000 ISSUES COULD CAUSE INTERRUPTION OF ALPHA-BETA'S BUSINESS
    

   
        Alpha-Beta cannot assure you that its business will not be interrupted
or impaired as a result of complications which may arise because of the
inability of computer systems and software to function properly with respect to
dates in the year 2000 and thereafter. Accordingly, Alpha-Beta has undertaken an
assessment of the year 2000 complications with respect to its information and
non-information systems. Alpha-Beta anticipates that the total costs to remedy
year 2000 issues will be approximately $300,000 ($250,000 for information
systems and $50,000 for non-information systems), which includes approximately
$100,000 in accelerated replacement costs for technology which Alpha-Beta would
have otherwise replaced within two years of the year 2000.
    

   
        Alpha-Beta has also begun to assess the year 2000 risks of third parties
with whom the Company has a material relationship. These material third parties
include clinical research organizations, consultants and statisticians involved
in the Company"S current Phase III clinical trial of Betafectin(R). Because
Alpha-Beta expects that its clinical trial of Betafectin(R) will be completed
prior to the year 2000, it does not believe that the potential risks of these
third parties will have a material effect on its business. However, risks
relating to the year 2000 could impact clinical programs, if any, existing at
such time.
    

   
        Alpha-Beta cannot assure you that its or its material third parties year
2000 conversion will be completed by such time. Alpha-Beta believes that in the
event of its most reasonably likely worst case scenario, Alpha-Beta will 
experience slower production runs of Betafectin(R).
    


                                   THE COMPANY

        Alpha-Beta is a Massachusetts corporation with its principal executive
offices at Three Biotech Park, One Innovation Drive, Worcester, Massachusetts
01605. Its telephone number is (508) 798-6900.


                                 USE OF PROCEEDS

   
        Alpha-Beta will not receive any proceeds from the sale of the Alpha-Beta
common stock under this prospectus.
    

   
               MATERIAL TERMS OF THE HFTP INVESTMENTS TRANSACTION
    

   
ISSUANCE OF THE ALPHA-BETA PREFERRED STOCK
    

   
        On October 21, 1998, Alpha-Beta entered into a securities purchase
agreement with HFTP Investments, pursuant to which the HFTP Investments (i)
purchased, on October 21, 1998, 1,500 shares of Alpha-Beta preferred stock in a
private placement transaction, and (ii) is obligated to purchase an additional
1,500 shares of preferred stock in a private placement transaction upon
effectiveness of the registration statement relating to this prospectus and the
satisfaction of certain other conditions which have been previously satisfied.
    

   
        The obligation of HFTP Investments to purchase the second tranche of
preferred stock is contingent upon Alpha-Beta's common stock not having been
suspended by the Nasdaq National Market or the SEC prior to the closing of the
second tranche of preferred stock and Alpha-Beta having not been 
notified of any pending or threatened proceeding or other action to delist or 
suspend the common stock prior to such time.
    

        The purchase price for both tranches of the Alpha-Beta Preferred Stock
is $1,000 per share, or $1,500,000 for the first tranche and $1,500,000 for the
second tranche.


                                       8
<PAGE>   11

   
        Alpha-Beta will use the net proceeds from the sale of the preferred
stock to partially fund its ongoing Phase III clinical trial of Betafectin(R) 
for the prevention of serious post-operative infections, as well as its novel
antifungal research program.
    

   
        In connection with the foregoing transaction, Alpha-Beta issued Reedland
Capital and World Capital an aggregate of 22,500 shares of Alpha-Beta common
stock and warrants exercisable for 25,000 shares of common stock as partial
consideration for their consulting services.
    

   
TERMS OF THE ALPHA-BETA PREFERRED STOCK
    

   
        The rights of the Alpha-Beta preferred stock are set forth in the
Certificate of Vote of Directors filed with the Secretary of State of
Massachusetts on October 21, 1998 (the "Certificate of Designations").
    

   
        Subject to certain anti-dilution provisions, the preferred stock is
convertible into shares of Alpha-Beta common stock pursuant to a formula (the
"Conversion Rate") whereby the purchase price of the shares of preferred stock
to be converted (plus interest at the rate of 6% per annum) is divided by a
conversion price equal to the lower of a cap and a price equal to a 15% discount
to the average closing price of the Alpha-Beta common stock for the five trading
days immediately preceding the date of conversion. Initially, the cap equals
$1.50. Upon issuance of the second tranche of preferred stock, the cap will be
reset at approximately $1.57. The Conversion Rate was $.9244 on October 21, 1998
and $.5950 on January 7, 1999. As an example of the application of the
Conversion Rate, 3,245,436 shares and 5,073,927 shares of common stock were
issuable upon conversion of the preferred stock on October 21, 1998 and January
7, 1999, respectively, assuming completion of both tranches of preferred stock
as of such dates. The preferred stock is convertible for a period of four years
commencing on the date of issuance and is subject to mandatory conversion upon
expiration of such four year period.
    

   
        The Certificate of Designations prohibits HFTP Investments from
converting any shares of the Alpha-Beta preferred stock to the extent such
conversion would result in HFTP Investments beneficially owning in excess of
4.99% of the outstanding shares of Alpha-Beta common stock following such
conversion.
    

   
        Upon the occurrence of any of the following events, HFTP Investments may
require Alpha-Beta to buy back the outstanding shares of Alpha-Beta preferred
stock at a premium equal to at least 130% of the original purchase price per
share of preferred stock repurchased (the "Buy-back Premium"):
    

   
     *      the merger or consolidation of the Alpha-Beta into another entity;
    

   
     *      the sale of all or substantially all of the assets of Alpha-Beta;
    

   
     *      the acceptance of a tender offer or exchange offer by the holders of
            more than 40% of the outstanding shares of Alpha-Beta common stock;
    

   
     *      the failure of the Alpha-Beta to obtain the effectiveness of the 
            resale registration statement;
    

   
     *      the suspension of sales under the resale registration statement;
    

   
     *      the suspension of trading in Alpha-Beta common stock on the Nasdaq
            National Market; or
    

   
     *      the failure of Alpha-Beta to convert shares of the Alpha-Beta 
            preferred stock as required.
    

   
        In the event of any liquidation, dissolution or winding up of
Alpha-Beta, the holders of the Alpha-Beta preferred stock are entitled to
receive cash, before any amount is paid to the holders of any other equity
securities of Alpha-Beta, in an amount per share of preferred stock outstanding
equal to the purchase price for such share of preferred stock ($1,000) plus
interest at the rate of 6% per annum. If the amounts available for distribution
are insufficient to pay the full amount due to the holders of the preferred
stock, Alpha-Beta shall distribute the available funds to such persons pro rata.
    

                                       9

<PAGE>   12


   
        The holders of the Alpha-Beta preferred stock have no voting rights
except as required by law or as specified in the Certificate of Designations.
Pursuant to the Certificate of Designations, the affirmative vote of the holders
of two-thirds of the outstanding shares of Alpha-Beta preferred stock is
required for (i) any authorization or issuance of securities senior or equal to
the preferred stock, (ii) any amendment to the Certificate of Designations or
Alpha-Beta's Restated Articles of Organization which would change or repeal any
of the rights of the preferred stock, (iii) any amendment to Alpha-Beta's
Restated Articles of Organization or By-Laws which would impair the rights of
the holders of the Alpha-Beta preferred stock relative to the holders of any
other securities of Alpha-Beta, (iv) any issuance of shares of Alpha-Beta
preferred stock other than pursuant to the securities purchase agreement, and
(v) any redemption or declaration or payment of a dividend with respect to the
Alpha-Beta common stock.
    


REGISTRATION OF CONVERSION SHARES


   
        Pursuant to the registration rights agreement between Alpha-Beta and
HFTP Investments, Alpha-Beta is required to register a number of shares of
common stock equal to at least 2.00 times the number of common stock issuable
upon conversion of the preferred stock. The 11,047,500 shares being registered
hereunder represents Alpha-Beta's good faith estimate as to the maximum number
of shares which may be offered by the selling stockholders. Alpha-Beta is
required to maintain the effectiveness of such registration until the earlier of
the sale of all of the shares of common stock issuable upon conversion of the
preferred stock under the resale registration statement or the saleability of
such shares pursuant to Rule 144(k) of the Securities Act. If Alpha-Beta fails
to cause or maintain such effectiveness, it may be required to pay penalties per
share of preferred stock outstanding equal to $15 plus $5 times the number of
days the registration statement is not effective (i.e., $45,000 plus $15,000 per
day assuming completion of the second tranche of preferred stock).

                              PLAN OF DISTRIBUTION

   
        The shares of Alpha-Beta common stock offered by this prospectus (the
"Shares") are being offered on behalf of the selling stockholders. Such Shares
may be sold or distributed from time to time by the selling stockholders, or by
donees or transferees of, or other successors in interest to, the selling
stockholders, directly to one or more purchasers or through brokers, dealers or
underwriters who may act solely as agents or may acquire such Shares as
principals, at market prices prevailing at the time of sale, at prices related
to such prevailing market prices, at negotiated prices, or at fixed prices,
which may be changed. The sale of the Shares offered hereby may be effected in
one or more of the following methods: (i) ordinary brokers' transactions; (ii)
transactions involving cross or block trades or otherwise on the Nasdaq National
Market; (iii) purchases by brokers, dealers or underwriters as principal and
resale by such purchasers for their own accounts pursuant to this prospectus;
(iv) "at the market" to or through market makers or into an existing market for
Alpha-Beta common stock; (v) in other ways not involving market makers or
established trading markets, including direct sales to purchasers or sales
effected through agents; (vi) through transactions in options, swaps or other 
derivatives (whether exchange-listed or otherwise); (vii) in privately 
negotiated transactions; (viii) to cover short sales; or (ix) any combination of
the foregoing.
    

   
        From time to time, one or more of the selling stockholders may pledge,
hypothecate or grant a security interest in some or all of the Shares owned by
them, and the pledgees, secured parties or persons to whom such Shares have been
hypothecated shall, upon foreclosure in the event of default, be deemed to be
selling stockholders hereunder. The number of Shares beneficially owned by those
selling stockholders who so transfer, pledge, donate or assign such Shares will
decrease as and when they take such actions. The plan of 
    

                                       11

<PAGE>   14
   
distribution for the Shares sold hereunder will otherwise remain unchanged,
except that the transferees, pledgees, donees or other successors will be
selling stockholders hereunder. In addition, a selling stockholder may, from
time to time, sell short the Shares, and in such instances, this prospectus may
be delivered in connection with such short sales and the shares of Alpha-Beta
common stock offered hereby may be used to cover such short sales.
    

   
        A selling stockholder may enter into hedging transactions with
broker-dealers and the broker-dealers may engage in short sales of Alpha-Beta
common stock in the course of hedging the positions they assume with such
selling stockholder, including, without limitation, in connection with
distributions of Alpha-Beta common stock by such broker-dealers. A selling
stockholder may also enter into option or other transactions with broker-dealers
that involve the delivery of the Shares to the broker-dealers, who may then
resell or otherwise transfer such shares of Alpha-Beta common stock. A selling
stockholder may also loan or pledge its Shares to a broker-dealer and the
broker-dealer may sell the Shares so loaned or upon a default may sell or
otherwise transfer the pledged Shares.
    

   
        Brokers, dealers, underwriters or agents participating in the
distribution of the Shares as agents may receive compensation in the form of
commissions, discounts or concessions from the selling stockholders and/or
purchasers of the Shares for whom such broker-dealers may act as agent, or to
whom they may sell as principal, or both (which compensation as to a particular
broker-dealer may be less than or in excess of customary commissions). The
selling stockholders and any broker-dealers who act in connection with the sale
of the Shares hereunder may be deemed to be "Underwriters" within the meaning of
the Securities Act, and any commissions they receive and proceeds of any sale of
the Shares may be deemed to be underwriting discounts and commissions under the
Securities Act. Neither Alpha-Beta nor any selling stockholders can presently
estimate the amount of such compensation. Alpha-Beta knows of no existing
arrangements between any selling stockholders, any other stockholder, broker,
dealer, underwriter or agent relating to the sale or distribution of the Shares.
    

   
        Alpha-Beta will pay substantially all of the expenses incident to the
registration, offering and sale of the Shares to the public other than
commissions or discounts of underwriters, broker-dealers or agents. Alpha-Beta
has also agreed to indemnify the selling stockholders and certain related
persons against certain liabilities, including liabilities under the Securities
Act.
    

   
        Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of
Alpha-Beta, Alpha-Beta has been advised that in the opinion of the SEC such
indemnification is against public policy as expressed in the Securities Act and
is therefore, unenforceable.

        All expenses referenced above will be borne by Alpha-Beta.


ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

        Alpha-Beta is a Massachusetts corporation. Reference is made to Chapter
156B, Section 13 of the Massachusetts Business Corporation Law (the "MBCL"),
which enables a corporation in its original articles of organization or an
amendment thereto to eliminate or limit the personal liability of a director for
monetary damages for violations of the director's fiduciary duty, except (i) for
any breach of the director's duty of loyalty to the corporation or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) pursuant to Sections
61 and 62 of the MBCL (providing for liability of directors for authorizing
unauthorized distributions and for making loans to directors, officers and
certain shareholders) or (iv) for any transaction from which a director derived
an improper personal benefit.

        Reference also is made to Chapter 156B, Section 67 of the MBCL, which
provides that a corporation may indemnify directors, officers, employees and
other agents and persons who serve at its request as directors, officers,
employees or other agents of another organization or who serve at its request in
any capacity with respect to any employee benefit plan, to the extent specified
or authorized by the articles of organization, a by-law adopted by the
stockholders or a vote adopted by the holders of a majority of the shares of
stock entitled to vote on the election of directors. Such indemnification may
include payment by the corporation of expenses incurred in defending a civil or
criminal action or proceeding in advance of the final disposition of such action
or proceeding, upon receipt of an undertaking by the person indemnified to repay
such payment if he shall be adjudicated to be not entitled to indemnification
under Section 67 which undertaking may be accepted without reference to the
financial ability of such person to make repayment. Any such indemnification may
be provided although the person to be indemnified is no longer an officer,
director, employee or agent of the corporation or of such other organization or
no longer serves with respect to any such employee benefit plan. No
indemnification shall be provided, however, for any person with respect to any
matter as to which he shall have been adjudicated in any proceeding not to have
acted in good faith in the reasonable belief that his action was in the best
interest of the corporation or to the extent that such matter relates to service
with respect to an employee benefit plan, in the best interest of the
participants or beneficiaries of such employee benefit plan.

        Article VI of the Restated Articles of Organization of Alpha-Beta
provides that, except under certain circumstances, directors of Alpha-Beta shall
not be personally liable to Alpha-Beta or its stockholders for monetary damages
for breach of fiduciary duties as a director.

        Article VI of the Restated Articles of Organization of Alpha-Beta
provides for indemnification of the officers and directors of Alpha-Beta to the
full extent permitted by applicable law.

   
        Insofar as indemnification for liabilities arising under the Securities
Act of 1933, as amended (the "Securities Act"), may be permitted to directors,
officers or persons controlling Alpha-Beta pursuant to the foregoing provisions,
the Commission has expressed its opinion that such indemnification is against
public policy as expressed in the Securities Act and is therefore unenforceable.

ITEM 17.  UNDERTAKINGS.

       (a)      The undersigned registrant hereby undertakes:

                (1) To file, during any period in which offers or sales are
       being made, a post-effective amendment to this registration statement:

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

                         (ii) To reflect in the prospectus any facts or events
                arising after the effective date of the registration statement
                (or the most recent post-effective amendment thereof) which,
                individually or in the aggregate, represent a fundamental change
                in the information set forth in the registration statement; and

                         (iii) To 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 (a)(1)(i) and (a)(1)(ii) herein do not
       apply if the information required to be included in a post-effective
       amendment by those paragraphs is contained in periodic reports filed by
       the undersigned registrant pursuant to Section 13 or Section 15(d) of the
       Exchange Act that are incorporated by reference in the registration
       statement;

                (2) That, for the purpose of determining any liability under the
       Securities Act, each such post-effective amendment shall be deemed to be
       a new registration statement relating to the securities 

                                      II-2

<PAGE>   19


       offered therein, and the offering of such securities at that time shall 
       be deemed to be the initial bona fide offering thereof; and

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

     (b)        The undersigned registrant 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.

     (c)        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
                provisions described under Item 15 above, 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 of 1933
                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 of 1933 and will be governed by the final
                adjudication of such issue.

                                WARRANT AGREEMENT

        THIS WARRANT AGREEMENT dated as of October 21, 1998, between Alpha-Beta
Technology, Inc., a Massachusetts corporation (the "Company"), and Reedland
Capital Partners (the "Holder").

                              W I T N E S S E T H:

        WHEREAS, the Company has engaged the Holder to act as a consultant to
the Company regarding certain financing alternatives; and

        WHEREAS, in consideration thereof, the Company has authorized the
issuance to the Holder of the warrant (the "Warrant") of the Company represented
by this Warrant Agreement, which Warrant entitles the Holder to purchase, upon
the terms and conditions hereinafter set forth, shares of Common Stock, par
value $.01 per share (the "Common Stock") of the Company;

        NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

                                    ARTICLE I

                                GRANT OF WARRANT

        This Warrant Agreement entitles the Holder to purchase up to six
thousand two hundred fifty (6,250) shares of Common Stock at a price per share
equal to the Exercise Price per share (as defined in Section 2.1 hereof).

                                   ARTICLE II

                       EXERCISE OF WARRANT; EXERCISE PRICE

        Section 2.1 EXERCISE PRICE. This Warrant Agreement shall entitle the
Holder, subject to the provisions of Article II and Article III, to purchase
from the Company the number of shares of Common Stock provided for in Article I,
at a purchase price equal to the product of (x) 1.25 multiplied by (y) the
closing trade price on the date hereof for a share of Common Stock on the Nasdaq
National Market as reported by Bloomberg (such price, which shall be



<PAGE>   2
listed on Schedule I and attached hereto upon determination, is hereinafter
referred to as the "Exercise Price"), which shall be payable in full in cash at
the time of exercise of this Warrant Agreement.

        Section 2.2 RIGHT TO EXERCISE THE WARRANT. This Warrant Agreement may be
exercised in full only, at any time during the period from the date hereof
through the date of the fifth anniversary of the date hereof (the "Exercise
Period").

        Section 2.3 PROCEDURE FOR EXERCISING THE WARRANT. The Holder may
exercise this Warrant Agreement by executing the Form of Election attached
hereto as EXHIBIT A and delivering it to the Company and tendering the requisite
aggregate Exercise Price for the number of shares of Common Stock subject to
this Warrant Agreement to the Company on any business day during normal business
hours (the date of receipt of such Form of Election and aggregate Exercise Price
by the Company is hereinafter referred to as the "Exercise Date") provided, that
in lieu of tendering the requisite aggregate Exercise Price in cash, the Holder
may elect to exercise this Warrant Agreement on a net basis whereupon (a) the
number of shares of Common Stock issued upon such exercise shall be reduced by
that number of shares which have an aggregate fair market value, based upon the
average closing price for the Company's Common Stock for the last ten trading
days prior to the Exercise Date, equal to the requisite aggregate Exercise Price
and (b) the Exercise Price shall be deemed to have been paid and satisfied by
the tender of such shares to the Company.

        Section 2.4 ISSUANCE OF SHARES OF COMMON STOCK. As soon as practicable
after the Exercise Date the Company shall (provided that it has received the
Form of Election duly executed, accompanied by payment of the Exercise Price
pursuant to Section 2.1 hereof for each of the shares of Common Stock to be
purchased) promptly cause certificates for the number of shares of Common Stock
to be issued in respect of this Warrant Agreement to be delivered to or upon the
order of the Holder, registered in such name as may be designated by such
holder; provided that if the Common Stock is to be registered in the name of any
entity or person other than the Holder, the Company may require evidence of
compliance by the Holder with all applicable securities laws.

                                   ARTICLE III

            RESERVATION AND AVAILABILITY OF COMMON STOCK; ADJUSTMENTS

        Section 3.1 RESERVATION OF COMMON STOCK. The Company covenants and
agrees that it will cause to be kept available out of its authorized and
unissued Common Stock, or its authorized and issued Common Stock held in its
treasury, the number of shares of Common Stock that will be sufficient to permit
the exercise in full of this Warrant Agreement.

        Section 3.2 COMMON STOCK TO BE DULY AUTHORIZED AND ISSUED, FULLY PAID
AND NON-ASSESSABLE. The Company covenants and agrees that it will take all such
action as may be




                                        2


<PAGE>   3
necessary to ensure that all shares of Common Stock delivered upon exercise of
the Warrant shall, at the time of delivery of the certificates for such shares,
be duly and validly authorized and issued and fully paid and non-assessable
shares.

        Section 3.3 COMMON STOCK RECORD DATE. Each person or entity in whose
name any certificate for shares of Common Stock is issued upon the exercise of
this Warrant Agreement shall for all purposes be deemed to have become the
holder of record of the shares of Common Stock represented thereby on, and such
certificate shall be dated, the date upon which the Form of Election was duly
executed and payment of the aggregate Exercise Price was made pursuant to
Section 2.1 hereof. Prior to the exercise of this Warrant Agreement, the Holder
shall not be entitled to any rights of a stockholder of the Company with respect
to the shares of Common Stock for which this Warrant Agreement shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

        Section 3.4 ADJUSTMENT FOR COMMON STOCK DIVIDENDS, SUBDIVISIONS AND
COMBINATIONS. In case the Company shall, at any time or from time to time, (i)
pay a dividend in Common Stock, or make a distribution in Common Stock, (ii)
subdivide its outstanding Common Stock into a greater number of shares, or (iii)
combine its outstanding Common Stock into a smaller number of shares (including
a recapitalization in connection with a consolidation or merger in which the
Company is the continuing corporation), then (a) the Exercise Price in effect at
the time of the record date for such dividend or of the effective date of such
subdivision or combination shall be adjusted by multiplying such Exercise Price
by a fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately before such event and the denominator of which is the
number of shares of Common Stock outstanding immediately after such event and
(b) the number of shares of Common Stock for which this Warrant Agreement may be
exercised immediately before such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the Exercise Price immediately
before such event and the denominator of which is the Exercise Price immediately
after such event.

        Section 3.5 REORGANIZATIONS. All rights to exercise this Warrant
Agreement shall terminate in the event of any Reorganization (as defined below),
liquidation or dissolution of the Company, provided that the Company shall have
given at least thirty (30) days prior written notice to the Holder that such
transaction or event was to be consummated or effected and that the failure to
exercise this Warrant Agreement prior to such transaction or event shall result
in the lapse and termination of this Warrant Agreement and any rights hereunder.
In case of any consolidation or merger of the Company with or into another
corporation (other than a merger or consolidation in which the Company is the
continuing corporation and which does not result in any reclassification of the
outstanding shares of Common Stock or the conversion of such outstanding shares
of Common Stock into shares of other stock or other securities or property), or
the sale or transfer of the property of the Company as an entirety or




                                        3


<PAGE>   4
substantially as an entirety (collectively such actions being hereinafter
referred to as "Reorganizations"), there shall be deliverable upon exercise of
this Warrant Agreement (in lieu of the number of shares of Common Stock
theretofore deliverable) the number of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock which would
otherwise have been deliverable upon the exercise of this Warrant Agreement
would have been entitled upon such Reorganization if this Warrant Agreement had
been exercised immediately prior to such Reorganization.

                                   ARTICLE IV

                HOLDER REPRESENTATIONS, WARRANTIES AND COVENANTS

        The Holder represents and warrants to and covenants with, the Company,
as follows:

        Section 4.1 INVESTMENT REPRESENTATIONS. It understands the risks of
investing in developing high technology companies such as the Company and can
afford a loss of its entire investment. It is acquiring the Warrant for
investment for its own account and not with the view to, or for resale in
connection with any distribution thereof. It understands that the Warrant and
the shares of Common Stock issuable upon exercise thereof have not been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
or any state blue sky laws, by reason of specified exemptions from the
registration provisions of the Securities Act and such laws. It acknowledges
that the Warrant and the shares of Common Stock issuable upon exercise thereof
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. It has been
advised or is aware of the provisions of Rule 144 promulgated under the
Securities Act, which permits the resale of shares purchased in a private
placement subject to the satisfaction of certain conditions and that such Rule
may not be available for resale of the shares. It has had an opportunity to
discuss the Company's business, management and financial affairs with its
management and has had the opportunity to review the Company's facilities.

        Section 4.2 NO CONFLICT. The Holder hereby represents and warrants that
(i) its acquisition of the Restricted Securities does not violate any law,
ordinance or regulation of any governmental entity or regulatory authority
having authority or jurisdiction over the Holder, and (ii) no order or
authorization of, consent from or filing with any court or governmental entity
or regulatory authority that has not been made or received (as applicable) is
required in connection with the Holder's acquisition of the Restricted
Securities.

        Section 4.3 RESTRICTIONS ON TRANSFERABILITY. Neither the Warrant, nor
the shares of Common Stock received upon exercise thereof, shall be
transferable, except upon the conditions specified in and in accordance with the
terms of this Article IV hereof.




                                        4

<PAGE>   5
        Section 4.4 RESTRICTIVE LEGEND. Each certificate representing shares of
the Company's Common Stock issuable upon exercise of the Warrant, or any other
securities issued in respect of the Common Stock issued upon exercise of the
Warrant, upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall be stamped or otherwise imprinted with a
legend in substantially the following form (in addition to any legend required
under applicable state securities laws):

        THE SHARES REPRESENTED HEREBY HAVE BEEN ACQUIRED BY THE HOLDER NAMED
        HEREON FOR ITS OWN ACCOUNT FOR INVESTMENT WITH NO INTENTION OF MAKING OR
        CAUSING TO BE MADE ANY PUBLIC DISTRIBUTION OF ALL OR ANY PORTION
        THEREOF; AND SUCH SECURITIES MAY NOT BE PLEDGED, SOLD OR IN ANY OTHER
        WAY TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
        FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS IN EFFECT AT
        THAT TIME, OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
        ISSUER THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

        Section 4.5 RESTRICTIONS ON, AND NOTICE OF, PROPOSED TRANSFERS. The
Holder agrees that prior to any proposed transfer of this Warrant or any of the
shares of Common Stock issuable upon exercise of this Warrant (collectively, the
"Restricted Securities"), the Holder shall give written notice to the Company of
its intention to effect such transfer. Each such notice shall describe the
manner and circumstances of the proposed transfer in sufficient detail, and
shall be accompanied by either (a) a written opinion of legal counsel who shall
be reasonably satisfactory to the Company, addressed to the Company and
reasonably satisfactory in form and substance to the Company's counsel, to the
effect that the proposed transfer of the Restricted Securities may be effected
without registration under the Securities Act or under any applicable state or
other securities laws (which opinion with respect to state or other securities
laws shall in any event be delivered if the "no-action" letter is delivered
pursuant to Section 4.4(b)) or (b) a "no-action" letter from the staff of the
Securities and Exchange Commission to the effect that the distribution of such
securities without registration will not result in a recommendation by the staff
of the Securities and Exchange Commission that action be taken with respect
thereto, whereupon the Holder shall be entitled to transfer such Restricted
Securities in accordance with the terms of the notice delivered to the Company.
Each certificate evidencing the Restricted Securities transferred as provided
above shall bear the appropriate restrictive legend set forth in Section 4.3
above, except that such certificate shall not bear such restrictive legend if
the opinion of counsel or "no-action" letter referred to above is to the further
effect that such legend is not required in order to comply with any provisions
of the Securities Act.

                                WARRANT AGREEMENT

        THIS WARRANT AGREEMENT dated as of October 21, 1998, between Alpha-Beta
Technology, Inc., a Massachusetts corporation (the "Company"), and Reedland
Capital Partners (the "Holder").

                              W I T N E S S E T H:

        WHEREAS, the Company has engaged the Holder to act as a consultant to
the Company regarding certain financing alternatives; and

        WHEREAS, in consideration thereof, the Company has authorized the
issuance to the Holder of the warrant (the "Warrant") of the Company represented
by this Warrant Agreement, which Warrant entitles the Holder to purchase, upon
the terms and conditions hereinafter set forth, shares of Common Stock, par
value $.01 per share (the "Common Stock") of the Company;

        NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

                                    ARTICLE I

                                GRANT OF WARRANT

        This Warrant Agreement entitles the Holder to purchase up to six
thousand two hundred fifty (6,250) shares of Common Stock at a price per share
equal to the Exercise Price per share (as defined in Section 2.1 hereof).

                                   ARTICLE II

                       EXERCISE OF WARRANT; EXERCISE PRICE

        Section 2.1 EXERCISE PRICE. This Warrant Agreement shall entitle the
Holder, subject to the provisions of Article II and Article III, to purchase
from the Company the number of shares of Common Stock provided for in Article I,
at a purchase price equal to the product of (x) 1.50 multiplied by (y) the
closing trade price on the date hereof for a share of Common Stock on the Nasdaq
National Market as reported by Bloomberg (such price, which shall be listed on
Schedule I and attached hereto upon determination, is hereinafter referred to as
the


<PAGE>   2
"Exercise Price"), which shall be payable in full in cash at the time of
exercise of this Warrant Agreement.

        Section 2.2 RIGHT TO EXERCISE THE WARRANT. This Warrant Agreement may be
exercised in full only, at any time during the period from the date hereof
through the date of the fifth anniversary of the date hereof (the "Exercise
Period").

        Section 2.3 PROCEDURE FOR EXERCISING THE WARRANT. The Holder may
exercise this Warrant Agreement by executing the Form of Election attached
hereto as EXHIBIT A and delivering it to the Company and tendering the requisite
aggregate Exercise Price for the number of shares of Common Stock subject to
this Warrant Agreement to the Company on any business day during normal business
hours (the date of receipt of such Form of Election and aggregate Exercise Price
by the Company is hereinafter referred to as the "Exercise Date") provided, that
in lieu of tendering the requisite aggregate Exercise Price in cash, the Holder
may elect to exercise this Warrant Agreement on a net basis whereupon (a) the
number of shares of Common Stock issued upon such exercise shall be reduced by
that number of shares which have an aggregate fair market value, based upon the
average closing price for the Company's Common Stock for the last ten trading
days prior to the Exercise Date, equal to the requisite aggregate Exercise Price
and (b) the Exercise Price shall be deemed to have been paid and satisfied by
the tender of such shares to the Company.

        Section 2.4 ISSUANCE OF SHARES OF COMMON STOCK. As soon as practicable
after the Exercise Date the Company shall (provided that it has received the
Form of Election duly executed, accompanied by payment of the Exercise Price
pursuant to Section 2.1 hereof for each of the shares of Common Stock to be
purchased) promptly cause certificates for the number of shares of Common Stock
to be issued in respect of this Warrant Agreement to be delivered to or upon the
order of the Holder, registered in such name as may be designated by such
holder; provided that if the Common Stock is to be registered in the name of any
entity or person other than the Holder, the Company may require evidence of
compliance by the Holder with all applicable securities laws.

                                   ARTICLE III

            RESERVATION AND AVAILABILITY OF COMMON STOCK; ADJUSTMENTS

        Section 3.1 RESERVATION OF COMMON STOCK. The Company covenants and
agrees that it will cause to be kept available out of its authorized and
unissued Common Stock, or its authorized and issued Common Stock held in its
treasury, the number of shares of Common Stock that will be sufficient to permit
the exercise in full of this Warrant Agreement.

        Section 3.2 COMMON STOCK TO BE DULY AUTHORIZED AND ISSUED, FULLY PAID
AND NONASSESSABLE. The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all shares of Common Stock delivered
upon exercise of the Warrant




                                        2

<PAGE>   3
shall, at the time of delivery of the certificates for such shares, be duly and
validly authorized and issued and fully paid and non-assessable shares.

        Section 3.3 COMMON STOCK RECORD DATE. Each person or entity in whose
name any certificate for shares of Common Stock is issued upon the exercise of
this Warrant Agreement shall for all purposes be deemed to have become the
holder of record of the shares of Common Stock represented thereby on, and such
certificate shall be dated, the date upon which the Form of Election was duly
executed and payment of the aggregate Exercise Price was made pursuant to
Section 2.1 hereof. Prior to the exercise of this Warrant Agreement, the Holder
shall not be entitled to any rights of a stockholder of the Company with respect
to the shares of Common Stock for which this Warrant Agreement shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

        Section 3.4 ADJUSTMENT FOR COMMON STOCK DIVIDENDS, SUBDIVISIONS AND
COMBINATIONS. In case the Company shall, at any time or from time to time, (i)
pay a dividend in Common Stock, or make a distribution in Common Stock, (ii)
subdivide its outstanding Common Stock into a greater number of shares, or (iii)
combine its outstanding Common Stock into a smaller number of shares (including
a recapitalization in connection with a consolidation or merger in which the
Company is the continuing corporation), then (a) the Exercise Price in effect at
the time of the record date for such dividend or of the effective date of such
subdivision or combination shall be adjusted by multiplying such Exercise Price
by a fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately before such event and the denominator of which is the
number of shares of Common Stock outstanding immediately after such event and
(b) the number of shares of Common Stock for which this Warrant Agreement may be
exercised immediately before such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the Exercise Price immediately
before such event and the denominator of which is the Exercise Price immediately
after such event.

        Section 3.5 REORGANIZATIONS. All rights to exercise this Warrant
Agreement shall terminate in the event of any Reorganization (as defined below),
liquidation or dissolution of the Company, provided that the Company shall have
given at least thirty (30) days prior written notice to the Holder that such
transaction or event was to be consummated or effected and that the failure to
exercise this Warrant Agreement prior to such transaction or event shall result
in the lapse and termination of this Warrant Agreement and any rights hereunder.
In case of any consolidation or merger of the Company with or into another
corporation (other than a merger or consolidation in which the Company is the
continuing corporation and which does not result in any reclassification of the
outstanding shares of Common Stock or the conversion of such outstanding shares
of Common Stock into shares of other stock or other securities or property), or
the sale or transfer of the property of the Company as an entirety or
substantially as an entirety (collectively such actions being hereinafter
referred to as





                                        3

<PAGE>   4
"Reorganizations"), there shall be deliverable upon exercise of this Warrant
Agreement (in lieu of the number of shares of Common Stock theretofore
deliverable) the number of shares of stock or other securities or property to
which a holder of the number of shares of Common Stock which would otherwise
have been deliverable upon the exercise of this Warrant Agreement would have
been entitled upon such Reorganization if this Warrant Agreement had been
exercised immediately prior to such Reorganization.

                                   ARTICLE IV

                HOLDER REPRESENTATIONS, WARRANTIES AND COVENANTS

        The Holder represents and warrants to and covenants with, the Company,
as follows:

        Section 4.1 INVESTMENT REPRESENTATIONS. It understands the risks of
investing in developing high technology companies such as the Company and can
afford a loss of its entire investment. It is acquiring the Warrant for
investment for its own account and not with the view to, or for resale in
connection with any distribution thereof. It understands that the Warrant and
the shares of Common Stock issuable upon exercise thereof have not been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
or any state blue sky laws, by reason of specified exemptions from the
registration provisions of the Securities Act and such laws. It acknowledges
that the Warrant and the shares of Common Stock issuable upon exercise thereof
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. It has been
advised or is aware of the provisions of Rule 144 promulgated under the
Securities Act, which permits the resale of shares purchased in a private
placement subject to the satisfaction of certain conditions and that such Rule
may not be available for resale of the shares. It has had an opportunity to
discuss the Company's business, management and financial affairs with its
management and has had the opportunity to review the Company's facilities.

        Section 4.2 NO CONFLICT. The Holder hereby represents and warrants that
(i) its acquisition of the Restricted Securities does not violate any law,
ordinance or regulation of any governmental entity or regulatory authority
having authority or jurisdiction over the Holder, and (ii) no order or
authorization of, consent from or filing with any court or governmental entity
or regulatory authority that has not been made or received (as applicable) is
required in connection with the Holder's acquisition of the Restricted
Securities.

        Section 4.3 RESTRICTIONS ON TRANSFERABILITY. Neither the Warrant, nor
the shares of Common Stock received upon exercise thereof, shall be
transferable, except upon the conditions specified in and in accordance with the
terms of this Article IV hereof.

        Section 4.4 RESTRICTIVE LEGEND. Each certificate representing shares of
the Company's Common Stock issuable upon exercise of the Warrant, or any other
securities issued in respect




                                        4

<PAGE>   5
of the Common Stock issued upon exercise of the Warrant, upon any stock split,
stock dividend, recapitalization, merger, consolidation or similar event, shall
be stamped or otherwise imprinted with a legend in substantially the following
form (in addition to any legend required under applicable state securities
laws):

        THE SHARES REPRESENTED HEREBY HAVE BEEN ACQUIRED BY THE HOLDER NAMED
        HEREON FOR ITS OWN ACCOUNT FOR INVESTMENT WITH NO INTENTION OF MAKING OR
        CAUSING TO BE MADE ANY PUBLIC DISTRIBUTION OF ALL OR ANY PORTION
        THEREOF; AND SUCH SECURITIES MAY NOT BE PLEDGED, SOLD OR IN ANY OTHER
        WAY TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
        FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS IN EFFECT AT
        THAT TIME, OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
        ISSUER THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

        Section 4.5 RESTRICTIONS ON, AND NOTICE OF, PROPOSED TRANSFERS. The
Holder agrees that prior to any proposed transfer of this Warrant or any of the
shares of Common Stock issuable upon exercise of this Warrant (collectively, the
"Restricted Securities"), the Holder shall give written notice to the Company of
its intention to effect such transfer. Each such notice shall describe the
manner and circumstances of the proposed transfer in sufficient detail, and
shall be accompanied by either (a) a written opinion of legal counsel who shall
be reasonably satisfactory to the Company, addressed to the Company and
reasonably satisfactory in form and substance to the Company's counsel, to the
effect that the proposed transfer of the Restricted Securities may be effected
without registration under the Securities Act or under any applicable state or
other securities laws (which opinion with respect to state or other securities
laws shall in any event be delivered if the "no-action" letter is delivered
pursuant to Section 4.4(b)) or (b) a "no-action" letter from the staff of the
Securities and Exchange Commission to the effect that the distribution of such
securities without registration will not result in a recommendation by the staff
of the Securities and Exchange Commission that action be taken with respect
thereto, whereupon the Holder shall be entitled to transfer such Restricted
Securities in accordance with the terms of the notice delivered to the Company.
Each certificate evidencing the Restricted Securities transferred as provided
above shall bear the appropriate restrictive legend set forth in Section 4.3
above, except that such certificate shall not bear such restrictive legend if
the opinion of counsel or "no-action" letter referred to above is to the further
effect that such legend is not required in order to comply with any provisions
of the Securities Act.

the Warrant shall, at the time of delivery of the certificates for such shares,
be duly and validly authorized and issued and fully paid and non-assessable
shares.

        Section 3.3 COMMON STOCK RECORD DATE. Each person or entity in whose
name any certificate for shares of Common Stock is issued upon the exercise of
this Warrant Agreement shall for all purposes be deemed to have become the
holder of record of the shares of Common Stock represented thereby on, and such
certificate shall be dated, the date upon which the Form of Election was duly
executed and payment of the aggregate Exercise Price was made pursuant to
Section 2.1 hereof. Prior to the exercise of this Warrant Agreement, the Holder
shall not be entitled to any rights of a stockholder of the Company with respect
to the shares of Common Stock for which this Warrant Agreement shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

        Section 3.4 ADJUSTMENT FOR COMMON STOCK DIVIDENDS, SUBDIVISIONS AND
COMBINATIONS. In case the Company shall, at any time or from time to time, (i)
pay a dividend in Common Stock, or make a distribution in Common Stock, (ii)
subdivide its outstanding Common Stock into a greater number of shares, or (iii)
combine its outstanding Common Stock into a smaller number of shares (including
a recapitalization in connection with a consolidation or merger in which the
Company is the continuing corporation), then (a) the Exercise Price in effect at
the time of the record date for such dividend or of the effective date of such
subdivision or combination shall be adjusted by multiplying such Exercise Price
by a fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately before such event and the denominator of which is the
number of shares of Common Stock outstanding immediately after such event and
(b) the number of shares of Common Stock for which this Warrant Agreement may be
exercised immediately before such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the Exercise Price immediately
before such event and the denominator of which is the Exercise Price immediately
after such event.

        Section 3.5 REORGANIZATIONS. All rights to exercise this Warrant
Agreement shall terminate in the event of any Reorganization (as defined below),
liquidation or dissolution of the Company, provided that the Company shall have
given at least thirty (30) days prior written notice to the Holder that such
transaction or event was to be consummated or effected and that the failure to
exercise this Warrant Agreement prior to such transaction or event shall result
in the lapse and termination of this Warrant Agreement and any rights hereunder.
In case of any consolidation or merger of the Company with or into another
corporation (other than a merger or consolidation in which the Company is the
continuing corporation and which does not result in any reclassification of the
outstanding shares of Common Stock or the conversion of such outstanding shares
of Common Stock into shares of other stock or other securities or property), or
the sale or transfer of the property of the Company as an entirety or




                                        3

substantially as an entirety (collectively such actions being hereinafter
referred to as "Reorganizations"), there shall be deliverable upon exercise of
this Warrant Agreement (in lieu of the number of shares of Common Stock
theretofore deliverable) the number of shares of stock or other securities or
property to which a holder of the number of shares of Common Stock which would
otherwise have been deliverable upon the exercise of this Warrant Agreement
would have been entitled upon such Reorganization if this Warrant Agreement had
been exercised immediately prior to such Reorganization.

        The Holder represents and warrants to and covenants with, the Company,
as follows:

        Section 4.1 INVESTMENT REPRESENTATIONS. It understands the risks of
investing in developing high technology companies such as the Company and can
afford a loss of its entire investment. It is acquiring the Warrant for
investment for its own account and not with the view to, or for resale in
connection with any distribution thereof. It understands that the Warrant and
the shares of Common Stock issuable upon exercise thereof have not been
registered under the Securities Act of 1933, as amended (the "Securities Act"),
or any state blue sky laws, by reason of specified exemptions from the
registration provisions of the Securities Act and such laws. It acknowledges
that the Warrant and the shares of Common Stock issuable upon exercise thereof
must be held indefinitely unless they are subsequently registered under the
Securities Act or an exemption from such registration is available. It has been
advised or is aware of the provisions of Rule 144 promulgated under the
Securities Act, which permits the resale of shares purchased in a private
placement subject to the satisfaction of certain conditions and that such Rule
may not be available for resale of the shares. It has had an opportunity to
discuss the Company's business, management and financial affairs with its
management and has had the opportunity to review the Company's facilities.

        Section 4.2 NO CONFLICT. The Holder hereby represents and warrants that
(i) its acquisition of the Restricted Securities does not violate any law,
ordinance or regulation of any governmental entity or regulatory authority
having authority or jurisdiction over the Holder, and (ii) no order or
authorization of, consent from or filing with any court or governmental entity
or regulatory authority that has not been made or received (as applicable) is
required in connection with the Holder's acquisition of the Restricted
Securities.

        Section 4.3 RESTRICTIONS ON TRANSFERABILITY. Neither the Warrant, nor
the shares of Common Stock received upon exercise thereof, shall be
transferable, except upon the conditions specified in and in accordance with the
terms of this Article IV hereof.

        Section 4.4 RESTRICTIVE LEGEND. Each certificate representing shares of
the Company's Common Stock issuable upon exercise of the Warrant, or any other
securities issued in respect of the Common Stock issued upon exercise of the
Warrant, upon any stock split, stock dividend, recapitalization, merger,
consolidation or similar event, shall be stamped or otherwise imprinted with a
legend in substantially the following form (in addition to any legend required
under applicable state securities laws):

        THE SHARES REPRESENTED HEREBY HAVE BEEN ACQUIRED BY THE HOLDER NAMED
        HEREON FOR ITS OWN ACCOUNT FOR INVESTMENT WITH NO INTENTION OF MAKING OR
        CAUSING TO BE MADE ANY PUBLIC DISTRIBUTION OF ALL OR ANY PORTION
        THEREOF; AND SUCH SECURITIES MAY NOT BE PLEDGED, SOLD OR IN ANY OTHER
        WAY TRANSFERRED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
        FOR SUCH SECURITIES UNDER THE SECURITIES ACT OF 1933, AS IN EFFECT AT
        THAT TIME, OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
        ISSUER THAT REGISTRATION IS NOT REQUIRED UNDER SAID ACT.

        Section 4.5 RESTRICTIONS ON, AND NOTICE OF, PROPOSED TRANSFERS. The
Holder agrees that prior to any proposed transfer of this Warrant or any of the
shares of Common Stock issuable upon exercise of this Warrant (collectively, the
"Restricted Securities"), the Holder shall give written notice to the Company of
its intention to effect such transfer. Each such notice shall describe the
manner and circumstances of the proposed transfer in sufficient detail, and
shall be accompanied by either (a) a written opinion of legal counsel who shall
be reasonably satisfactory to the Company, addressed to the Company and
reasonably satisfactory in form and substance to the Company's counsel, to the
effect that the proposed transfer of the Restricted Securities may be effected
without registration under the Securities Act or under any applicable state or
other securities laws (which opinion with respect to state or other securities
laws shall in any event be delivered if the "no-action" letter is delivered
pursuant to Section 4.4(b)) or (b) a "no-action" letter from the staff of the
Securities and Exchange Commission to the effect that the distribution of such
securities without registration will not result in a recommendation by the staff
of the Securities and Exchange Commission that action be taken with respect
thereto, whereupon the Holder shall be entitled to transfer such Restricted
Securities in accordance with the terms of the notice delivered to the Company.
Each certificate evidencing the Restricted Securities transferred as provided
above shall bear the appropriate restrictive legend set forth in Section 4.3
above, except that such certificate shall not bear such restrictive legend if
the opinion of counsel or "no-action" letter referred to above is to the further
effect that such legend is not required in order to comply with any provisions
of the Securities Act.

                                WARRANT AGREEMENT

        THIS WARRANT AGREEMENT dated as of October 21, 1998, between Alpha-Beta
Technology, Inc., a Massachusetts corporation (the "Company"), and World Capital
Funding, LLC (the "Holder").

                              W I T N E S S E T H:

        WHEREAS, the Company has engaged the Holder to act as a consultant to
the Company regarding certain financing alternatives; and

        WHEREAS, in consideration thereof, the Company has authorized the
issuance to the Holder of the warrant (the "Warrant") of the Company represented
by this Warrant Agreement, which Warrant entitles the Holder to purchase, upon
the terms and conditions hereinafter set forth, shares of Common Stock, par
value $.01 per share (the "Common Stock") of the Company;

        NOW, THEREFORE, in consideration of the premises and the mutual
agreements herein set forth, the parties hereby agree as follows:

                                    ARTICLE I

                                GRANT OF WARRANT

        This Warrant Agreement entitles the Holder to purchase up to six
thousand two hundred fifty (6,250) shares of Common Stock at a price per share
equal to the Exercise Price per share (as defined in Section 2.1 hereof).

                                   ARTICLE II

                       EXERCISE OF WARRANT; EXERCISE PRICE

        Section 2.1 EXERCISE PRICE. This Warrant Agreement shall entitle the
Holder, subject to the provisions of Article II and Article III, to purchase
from the Company the number of shares of Common Stock provided for in Article I,
at a purchase price equal to the product of (x) 1.50 multiplied by (y) the
closing trade price on the date hereof for a share of Common Stock on the Nasdaq
National Market as reported by Bloomberg (such price, which shall be listed on
Schedule I and attached hereto upon determination, is hereinafter referred to as
the


<PAGE>   2
"Exercise Price"), which shall be payable in full in cash at the time of
exercise of this Warrant Agreement.

        Section 2.2 RIGHT TO EXERCISE THE WARRANT. This Warrant Agreement may be
exercised in full only, at any time during the period from the date hereof
through the date of the fifth anniversary of the date hereof (the "Exercise
Period").

        Section 2.3 PROCEDURE FOR EXERCISING THE WARRANT. The Holder may
exercise this Warrant Agreement by executing the Form of Election attached
hereto as EXHIBIT A and delivering it to the Company and tendering the requisite
aggregate Exercise Price for the number of shares of Common Stock subject to
this Warrant Agreement to the Company on any business day during normal business
hours (the date of receipt of such Form of Election and aggregate Exercise Price
by the Company is hereinafter referred to as the "Exercise Date") provided, that
in lieu of tendering the requisite aggregate Exercise Price in cash, the Holder
may elect to exercise this Warrant Agreement on a net basis whereupon (a) the
number of shares of Common Stock issued upon such exercise shall be reduced by
that number of shares which have an aggregate fair market value, based upon the
average closing price for the Company's Common Stock for the last ten trading
days prior to the Exercise Date, equal to the requisite aggregate Exercise Price
and (b) the Exercise Price shall be deemed to have been paid and satisfied by
the tender of such shares to the Company.

        Section 2.4 ISSUANCE OF SHARES OF COMMON STOCK. As soon as practicable
after the Exercise Date the Company shall (provided that it has received the
Form of Election duly executed, accompanied by payment of the Exercise Price
pursuant to Section 2.1 hereof for each of the shares of Common Stock to be
purchased) promptly cause certificates for the number of shares of Common Stock
to be issued in respect of this Warrant Agreement to be delivered to or upon the
order of the Holder, registered in such name as may be designated by such
holder; provided that if the Common Stock is to be registered in the name of any
entity or person other than the Holder, the Company may require evidence of
compliance by the Holder with all applicable securities laws.

                                   ARTICLE III

            RESERVATION AND AVAILABILITY OF COMMON STOCK; ADJUSTMENTS

        Section 3.1 RESERVATION OF COMMON STOCK. The Company covenants and
agrees that it will cause to be kept available out of its authorized and
unissued Common Stock, or its authorized and issued Common Stock held in its
treasury, the number of shares of Common Stock that will be sufficient to permit
the exercise in full of this Warrant Agreement.

        Section 3.2 COMMON STOCK TO BE DULY AUTHORIZED AND ISSUED, FULLY PAID
AND NONASSESSABLE. The Company covenants and agrees that it will take all such
action as may be necessary to ensure that all shares of Common Stock delivered
upon exercise of the Warrant




                                        2


<PAGE>   3
shall, at the time of delivery of the certificates for such shares, be duly and
validly authorized and issued and fully paid and non-assessable shares.

        Section 3.3 COMMON STOCK RECORD DATE. Each person or entity in whose
name any certificate for shares of Common Stock is issued upon the exercise of
this Warrant Agreement shall for all purposes be deemed to have become the
holder of record of the shares of Common Stock represented thereby on, and such
certificate shall be dated, the date upon which the Form of Election was duly
executed and payment of the aggregate Exercise Price was made pursuant to
Section 2.1 hereof. Prior to the exercise of this Warrant Agreement, the Holder
shall not be entitled to any rights of a stockholder of the Company with respect
to the shares of Common Stock for which this Warrant Agreement shall be
exercisable, including, without limitation, the right to vote, to receive
dividends or other distributions or to exercise any preemptive rights and shall
not be entitled to receive any notice of any proceedings of the Company, except
as provided herein.

        Section 3.4 ADJUSTMENT FOR COMMON STOCK DIVIDENDS, SUBDIVISIONS AND
COMBINATIONS. In case the Company shall, at any time or from time to time, (i)
pay a dividend in Common Stock, or make a distribution in Common Stock, (ii)
subdivide its outstanding Common Stock into a greater number of shares, or (iii)
combine its outstanding Common Stock into a smaller number of shares (including
a recapitalization in connection with a consolidation or merger in which the
Company is the continuing corporation), then (a) the Exercise Price in effect at
the time of the record date for such dividend or of the effective date of such
subdivision or combination shall be adjusted by multiplying such Exercise Price
by a fraction, the numerator of which is the number of shares of Common Stock
outstanding immediately before such event and the denominator of which is the
number of shares of Common Stock outstanding immediately after such event and
(b) the number of shares of Common Stock for which this Warrant Agreement may be
exercised immediately before such event shall be adjusted by multiplying such
number by a fraction, the numerator of which is the Exercise Price immediately
before such event and the denominator of which is the Exercise Price immediately
after such event.

        Section 3.5 REORGANIZATIONS. All rights to exercise this Warrant
Agreement shall terminate in the event of any Reorganization (as defined below),
liquidation or dissolution of the Company, provided that the Company shall have
given at least thirty (30) days prior written notice to the Holder that such
transaction or event was to be consummated or effected and that the failure to
exercise this Warrant Agreement prior to such transaction or event shall result
in the lapse and termination of this Warrant Agreement and any rights hereunder.
In case of any consolidation or merger of the Company with or into another
corporation (other than a merger or consolidation in which the Company is the
continuing corporation and which does not result in any reclassification of the
outstanding shares of Common Stock or the conversion of such outstanding shares
of Common Stock into shares of other stock or other securities or property), or
the sale or transfer of the property of the Company as an entirety or
substantially as an entirety (collectively such actions being hereinafter
referred to as




                                        3

<PAGE>   4

"Reorganizations"), there shall be deliverable upon exercise of this Warrant
Agreement (in lieu of the number of shares of Common Stock theretofore
deliverable) the number of shares of stock or other securities or property to
which a holder of the number of shares of Common Stock which would otherwise
have been deliverable upon the exercise of this Warrant Agreement would have
been entitled upon such Reorganization if this Warrant Agreement had been
exercised immediately prior to such Reorganization.

be reasonably satisfactory to the Company, addressed to the Company and
reasonably satisfactory in form and substance to the Company's counsel, to the
effect that the proposed transfer of the Restricted Securities may be effected
without registration under the Securities Act or under any applicable state or
other securities laws (which opinion with respect to state or other securities
laws shall in any event be delivered if the "no-action" letter is delivered
pursuant to Section 4.4(b)) or (b) a "no-action" letter from the staff of the
Securities and Exchange Commission to the effect that the distribution of such
securities without registration will not result in a recommendation by the staff
of the Securities and Exchange Commission that action be taken with respect
thereto, whereupon the Holder shall be entitled to transfer such Restricted
Securities in accordance with the terms of the notice delivered to the Company.
Each certificate evidencing the Restricted Securities transferred as provided
above shall bear the appropriate restrictive legend set forth in Section 4.3
above, except that such certificate shall not bear such restrictive legend if
the opinion of counsel or "no-action" letter referred to above is to the further
effect that such legend is not required in order to comply with any provisions
of the Securities Act.
