                                EXPLANATORY NOTE

           Interpharm Holdings, Inc. (formerly known as Atec Group, Inc.,
"Interpharm") is filing this registration statement on Form S-8 to register (i)
1,953,300 of its $.01 par value per shares common stock authorized for issuance
under the Atec Group, Inc. 2000 Flexible Stock Plan, now known as the Interpharm
Holdings, Inc. 2000 Flexible Stock Plan (the "Plan") and 25,0000 shares of
common stock authorized for issuance pursuant to an option granted to
Interpharm's former counsel. The Plan was approved by Interpharm Holdings,
Inc.'s shareholders at its annual meeting on January 9, 2001. The Plan provides
for the issuance of stock options for the purchase of 10,000,000 shares of
Interpharm Holdings Inc.'s Common Stock plus an annual increase, effective on
the first day of each calendar year, equal to 10% of the number of outstanding
shares of Common Stock as of the first day of each calendar year, but in no
event more than 20,000,000 shares in the aggregate.

           On May 30, 2003, Atec Group, Inc. completed a sale of its computer
operations to Baar Group, Inc., which also assumed substantially all of Atec's
liabilities. The owners of Baar are the following former members of Atec's
management: Ashok Rametra, Balwinder Singh Bathla, Rajnish Rametra, and Arvin
Gulati. Ashok Rametra and Rajnish Rametra are brothers of Surinder Rametra,
Atec's former Chairman, a current Interpharm Director and Interpharm's Director
of Business Development.

           On the same day, Atec also completed the previously announced
acquisition of all the capital stock of Interpharm, Inc., a New York
corporation, making it a wholly owned subsidiary, and changed its name to
Interpharm Holdings, Inc. Interpharm, Inc. is in the business of developing,
manufacturing, and distributing generic pharmaceutical products in the United
States. Interpharm, Inc. currently markets 20 products, representing various
dosage strengths for 11 distinct drugs that it manufactures. Interpharm, Inc.
markets its products primarily to wholesalers and drug distributors principally
through its internal sales staff as well as independent sales representatives

           The previous owners of the Interpharm, Inc. capital stock are Raj
Sutaria, Mona Rametra, Ravi Sutaria, and Perry Sutaria. Mona Rametra is the
daughter-in-law of Surinder Rametra. Mona Rametra is also the daughter of Dr.
Maganlal K. Sutaria, the current Chairman of the Board of Directors of
Interpharm. Although Dr. Sutaria did not own any Interpharm, Inc. stock, his
other two children (i.e. Mona Rametra's brothers) and his nephew, Ravi Sutaria,
owned the balance of Interpharm, Inc.'s common stock. Ravi Sutaria is the son of
Bhupatlal K. Sutaria, the Company's President and a member of its Board of
Directors.

           In consideration for the sale of the Atec computer operations to
Baar, the Company received proceeds of approximately $2.7 million, and Baar
assumed approximately $2.6 million in liabilities. The proceeds consisted of
promissory notes in the aggregate amount of $1.75 million and cash of
approximately $.9 million. This figure is based upon a base purchase price of
$4,278,184, less $569,332 in closing adjustments

           In exchange for the capital stock of Interpharm, Inc., its former
shareholders received 6,151,178 shares of Interpharm Holdings, Inc. Common Stock
and 2,050,393 shares of its Series K Convertible Preferred Stock. A complete
description of the Series K Stock may be found in Atec's definitive proxy
materials filed with the Securities and Exchange Commission (the "SEC") on May
2, 2003.

           A complete description of the terms of the Baar transaction and the
acquisition of Interpharm, Inc., are contained in the Company proxy materials
filed with the SEC on May 2, 2003, and the Baar and Interpharm, Inc. agreements
annexed thereto.

       Of the 1,953,300 Plan shares being registered 1,150,000 are to be issued
pursuant to the exercise of options held by four individuals. These four
individuals have agreements with Interpharm Holdings, Inc. which allow them to
sell no more than a combined total of 85,000 shares per calendar month.
