(FORM OF)

LOCK-UP AGREEMENT

This lock-up Agreement (this “Lock-Up Agreement”), dated as of November 30, 2003, has been entered into by and between

(A) Powerwave Technologies, Inc., a company duly organized and existing under the laws of the State of Delaware and having offices at 1801 E. St Andrew Place, Santa Ana, CA 92705, USA, (“Parent”); and

(B) ___________, (________), (the “Shareholder”).

WHEREAS, the Parent and LGP Allgon Holding AB, (556346 – 2620), a company organized under the laws of Sweden (the “Company”), have agreed to a strategic combination transaction, pursuant to which the Parent will effect a tender offer for the Company’s outstanding shares (the “Offer”).

WHEREAS, as of the date hereof, the Shareholder is the beneficial owner or record holder of              shares of capital stock of the Company and has granted the Parent an option to purchase (the “Option”) these shares and any other shares of the Company acquired by the Shareholder after the date hereof and prior to the Parent exercising the Option as set forth in the option agreement between the Parent and the Shareholder dated as of the date hereof (the “Option Agreement”).

WHEREAS, upon Parent’s exercise of the Option, the Parent will issue to the Shareholder, and the Shareholder will be the beneficial owner or record holder of such number of newly issued shares of Parent Common Stock as the Shareholder shall receive as consideration for the shares sold to the Parent under the Option Agreement (the “Parent Shares”). For the sake of clarity, shares or any other securities relating to the Parent purchased in the market or otherwise acquired by the Shareholder shall not be considered to be Parent Shares.

WHEREAS, as a condition to the Parent’s willingness to commence the Offer, the Parent has required that the Shareholder enter into, and the Shareholder has agreed to enter into, this Lock-Up Agreement and the Option Agreement.

NOW, THEREFORE, in consideration of the foregoing and the representations, warranties, covenants and agreements herein contained, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Restrictions on Transfer

During a period commencing on the date upon which the Shareholder becomes the beneficial owner or record holder of the Parent Shares and ending six (6) months after the date of commencement of settlement of consideration in the Offer (the “Lock-Up Period”), the Shareholder will not, without the prior written consent of the Parent, which consent shall not be unreasonably withheld or delayed, (i) offer, sell, assign, transfer, pledge, contract to sell, or otherwise dispose of any Parent Shares, (ii) enter into any swap, hedge or similar agreement or arrangement that transfers, in whole or in part, the economic risk of ownership of the Parent Shares or securities convertible into or exchangeable into Parent Shares, or (iii) engage in any short selling of the Parent Shares. The Parent may impose stop-transfer instructions with respect to the Parent Shares subject to the foregoing restrictions until the end of the Lock-Up Period.

2. Permitted Transfers

Notwithstanding Section 1 of this Lock-Up Agreement, the Shareholder may transfer all or part of the Parent Shares as follows: (i) the Shareholder may transfer the Parent Shares as a bona fide gift or gifts, provided that the donee or donees thereof agree in writing to be bound by the restrictions set forth herein, (ii) if the Shareholder is an individual, the Parent Shares may be transferred either during the Shareholder’s lifetime or on death by will or intestacy to any immediate family member or to any trust for the direct or indirect benefit of the Shareholder or the immediate family of the Shareholder, provided that such immediate family member or the trustee of the trust agrees in writing to be bound by the restrictions set forth herein, and provided further that any such transfer does not involve a disposition for value, (iii) the Shareholder may transfer the Parent Shares to any entity over which the Shareholder has a controlling influence (alone or together with other shareholders of the Parent who are bound by an agreement similar to this Lock-Up Agreement), to any company within the Skanditek Industriförvaltning AB group of companies or to any member of the Gottschlich family, provided that such entity or individual agrees in writing to be bound by the restrictions set forth herein, (iv) if the Shareholder comes into serious financial difficulty (considerable risk of bankruptcy), the Shareholder may, after consultation with the Parent regarding how such measure should be taken in order to take the best interest of the shareholders of the Parent into account, transfer, use as collateral for a loan to the Shareholder or enter into any similar financial arrangement in respect of the necessary number of the Parent Shares, and (v) if a public offer relating to the Parent Shares will be launched either by a third party or by the Parent itself during the Lock-Up Period, the Shareholder may accept such offer for the Parent Shares held by the Shareholder, provided that the board of directors of the Parent has recommended the offer.
